With XVT, CTOS developers can develop portable user interface applications between CTOS character and Presentation Manager (PM) based workstations.  XVT applications can easily be ported to other GUIs such as Motif, Open Look, and Microsoft Windows simply by recompiling and linking with a different XVT library.  $(SB)With this high degree of portability, XVT does not take a least common denominator approach to supporting the underlying window systems.  XVT contains functions to manipulate windows, draw text and graphics, allocate memory, process events and messages, display menus and dialog boxes, handle file IO, and print.  XVT's rich API avoids the level of complexity of the underlying window systems.  Consequently, $(PGNY,N,0)$(PGA2)$(SC)programming to XVT is easier than programming to the underlying window system. $(ASChead1)$(BY)$(PS320)$(FFHelvetica)$(CR4,5)$(ASRhead1)$(IL1008)$(IF64528)$(LN360,360,0)$(KTY)$(KFY)$(HP2)$(NS1)$(CT2)$(SB)$(SL)$(OY)$(CR0,0)1.3$(ON)	S$(ASC)ystem Service	$(BN)$(PS200)$(FFNew Century Schoolbook)$(ASR)$(IL558)$(IF0)$(LN160,240,0)$(KTN)$(KFN)$(HP0)$(NS0)$(CT0)$(SB)$(SM)XVT on CTOS is implemented by means of one of two system services;  one for character workstations (XVTCH) and one for PM workstations (XVTPM).  XVT function calls from the application are handled by the appropriate XVT System Service installed on the workstation.  Consequently, XVT applications support a common executable file for both CTOS PM and character environments.  With a common application binary interface (ABI), software maintenance, support, and development are greatly reduced for the XVT application developer.  $(SB)Users running more than one XVT application can realize substantial memory savings from the system service versus a linkedin library.  The system service allows each XVT application to require 250KB less of memory usage than applications that have XVT libraries linked in.  $(SB)The system service makes XVT applications more extensible.  Users can take advantage of new XVT enhancements and modifications by installing a new system service instead of waiting for a revision release from the application developer.$(ASChead1)$(BY)$(PS320)$(FFHelvetica)$(CR4,6)$(ASRhead1)$(IL1008)$(IF64528)$(LN360,360,0)$(KTY)$(KFY)$(HP2)$(NS1)$(CT2)$(SB)$(SL)$(OY)$(CR0,0)1.4$(ON)	$(ASC)Graphics	$(BN)$(PS200)$(FFNew Century Schoolbook)$(ASR)$(IL558)$(IF0)$(LN160,240,0)$(KTN)$(KFN)$(HP0)$(NS0)$(CT0)$(SB)$(SM)XVT provides a standard set of drawing primitives consisting of a pen, a brush, a font, and a drawing mode for drawing shapes such as rectangles, ovals, pie segments, and polygons.  A pen is used to draw outlines of shapes being specified in terms of width, color, and style.  A brush is used to draw a pattern of pixels within a geometric shape.  A font consists of a style (bold, italic, etc.), a point size, and family (Times, Helvetica, etc.).  A drawing mode can be used to implement pixel block moves (BitBlt) that support logical operations (OR, XOR, etc.).  Graphics primitives are not supported under XVTCH since XVTCH operates in a character environment.$(ASChead1)$(BY)$(PS320)$(FFHelvetica)$(PGA3)$(SC)$(CR4,7)$(ASRhead1)$(IL1008)$(IF64528)$(LN360,360,0)$(KTY)$(KFY)$(HP2)$(NS1)$(CT2)$(SB)$(SL)$(OY)$(CR0,0)1.5$(ON)	$(ASC)Text Edit	$(BN)$(PS200)$(FFNew Century Schoolbook)$(ASR)$(IL558)$(IF0)$(LN160,240,0)$(KTN)$(KFN)$(HP0)$(NS0)$(CT0)$(SB)$(SM)XVT allows multiple text edit areas in one window.

Additionally, an API is provided so the application (as well as XVT itself) can identify a topic based on the context the user is in.  Once a topic is displayed, a sizeable and moveable text window containing the help text is presented to the user.  By clicking on highlighted words that are of interest to them, users may navigate between topics using hyperlinks.  Help topics may also be started from a dialog box that lists the topics contained in the help file.  The help system reads topics from a system help file as well as an application help file.  Additional topics in other help files may be viewed by selecting a new help file from within the help system.

This mainly effects the SG2400, SG3000, SG3400, SG4000, SG6000, and SG7000.  There is no problem running XVTCH Real Mode Library applications under CTOS II or CTOS I$(SL).$(BN)$(IL974)$(IF65120)$(KFN)$(TBL960)$(SB)$(SM)	When running an XVT application under BTOS II 3.2 on a system with EV video hardware (B28EV and B38EV), the available coordinates are shifted to the right.  The XVT application will only show half of the rightmost border of the main window and will allow you to resize a window so that only half of its rightmost border is visible.$(SB)	When running an XVT application on an SG2000 with a B25D1 monitor, XVT will load a smaller font which results in a busy screen when trying to display lots of text and dialog boxes.$(SB)	After running an XVT application via Cluster View, the system font is not reloaded.  Since the XVT font closely resembles the system font, this may not be noticeable.  XVT cannot prevent this from happening.$(PGNY,N,0)$(PGA14)$(SC)$(SB)	The B27 is not supported in this release.$(SB)	When the server is running CTOSXE 3.0, cluster workstations may not be able to see the disks on the server.  This is caused by a bug in CTOSXE 3.0.  It is fixed in CTOSXE 3.0.5.	$(SB)	Hyperlinked help topics may not be started in circular fashion.  For example, if topic A starts topic B, then topic A may not be restarted from topic B.  While this will not cause a system crash or loss of data, the system may not be able to Backtrack or Return successfully to the ancestors of the launched topics.$(SB)	XVTCH 2.1 treats grayscale (e.g. GS1) monitors with a VGA graphics adapter as a black and white monitor.  It does not take advantage of the monitor's grayscale feature.$(SB)	If a user opens a very large number of dialog boxes at the same time (on the order of 1520), the XVTCH 2.1 service's stack may overflow.  This causes unpredictable behavior, eventually leading to a system crash.  The XVTCH 2.1 System Service cannot protect against this condition.  Client application developers must design their applications so that this condition does not occur.$(SB)	On some systems, if a user uses Context Manager to switch between contexts that use the character mode mouse (such as XVTCH), ghost cursors can be left on the screen.  This is a Context ManagerVAM interaction problem.  XVTCH cannot compensate for it.$(SB)	On CTOS II 3.3.3, all mouse clicks behave as if the shift button is up.  This prevents the use of shift$(SI)click. This is corrected in newer versions of CTOS.$(SB)	When the $(IY)<$(SA)>$(IN) directory is full, Context Manager is unable to load the XVTCH font on behalf of an XVTCH application.  When this occurs, the application's borders and dialog boxes will not appear correctly.  Delete files in the $(IY)<$(SA)>$(IN) directory to remedy  the problem.  $(SB)	Background color for text is implemented to a very limited extent.  Background color is only enabled if the foreground color is WHITE. (Internally, XVT reverses WHITE and BLACK, so application requests for WHITE text result in BLACK text.  This should not be apparent to users of XVT applications).  $(SB)	The minimum size for a window is three lines.$(PGA15)$(SC)$(SB)	XVTCH does not print correctly on a plotter.$(SB)	When entering the name of a file to open in the edit field of the standard open file dialog,  you must type the entire file specification, including the node name.  For example, to access a file on the server, you would type $(IY){server}[sys]<sys>config.sys$(IN) instead of $(IY)[sys]<sys>config.sys$(IN).$(SB)	On real mode systems, the standard open file dialog may not display all nodes.  To remedy this problem, merge $(IY)NetRq.txt$(IN) into the local request.sys file.  $(IY)NetRq.txt$(IN) is found on installation diskette 1 or $(IY)[Qic1]$(IN) of the CUI installation tape.$(SB)	The OVERTYPE key is not supported in this release.  Using the OVERTYPE key when entering text has no effect on text entry.$(SB)	On the SG3000 video attributes such as bold and underline are not supported.  However, color can be specified for character attributes that XVT supports by specifying 'yes' for the fields StdVgaBold and StdVgaUnderLine in the $(IY)config.sys$(IN) file.  This will cause colors from the XVT color palette to be used when XVT applications try to display bold or underline text.$(IL558)$(IF0)$(TB)$(SB)The following items are known restrictions and limitations with of the R2.1.8 release of the XVTCH System Service:$(IL974)$(IF65120)$(TBL960)$(SB)	The attributes which distinguish accelerators and menu mnemonics can be difficult to distinguish on the SG 1000 Open Notebook Workstation.$(PS360)$(FFHelvetica)$(PGA16)$(SC)$(PGNY,O,0)$(PGA17)$(SC)$(ASCsectionhead)$(BY)$(CR4,28)$(ASRsectionhead)$(IL0)$(IF0)$(LN240,400,720)$(KTY)$(KFY)$(TB)$(HP1)$(NS1)$(SB)$(SL)$(ASCsectionnumber)$(BN)$(CR0,0)Section $(OY)7$(ON)	$(ASC)$(BY)
