The Question is: Hi When trying to run a fortran program in debug mode i get an error message which says - %DEBUG-F-UNAOPNDIS, Unable to open display _WSA1: I have compiled this test program with the command: - FORTRAN/G_FLOATING/DEBUG/NOOPTIMIZE/NOLIST/EXTENDED_SOURCE and also linked with the link/debug command I am using a "Kea" terminal. Is this a terminal issue or I need something in my Debug.ini file Right now I have this command in my login.com DEFINE/NOLOG DBG$INIT "DEBUG.INI" and following are in the debug.ini file set module/all set mode screen set output term (This is what I get on logging in - to help in the version information OpenVMS Alpha Operating System, Version V6.2-1H2) Thanks Ajay The Answer is :
This has nothing to do with the way your program is compiled or linked,
nor is it affected by the presence or contents of your DEBUG.INI file.
For some reason you have a DECwindows display device defined in your
process which is not working. Use SHOW DISPLAY to see it, it may be an
artifact of your login procedures.
By default, if DEBUG sees a display, it will attempt to activate the
DECwindows interface. Since it is unable to open the display, an error
message is issued and DEBUG fails to activate.
At this point there are two choices, either provide DEBUG with an
appropriate DECwindows server, or make DEBUG use the character cell
interface.
You could achieve the former by installing X server software, such as
eXcursion on your PC and ensuring that the display is defined
correctly. The DECwindows interface is a GUI with point and click
commands. In many respects it is more powerful than the traditional
character cell interface.
To make DEBUG use the character cell interface, you could delete the
display (since you don't seem to be using it and it's not working
anyway) with SET DISPLAY/DELETE. See HELP for this command first as
there a few caveats. The success may depend on where the display was
created and whether the display is in use by another process.
Should you wish to force DEBUG to use the character cell interface
while retaining a DECwindows display define the logical name:
$ DEFINE DBG$DECW$DISPLAY " " ! must be a space character
