RE: Assume keyword on display file the is used by service program

Thanks Michael.  The problem is gone after I changed the service program
to close and open the display file.

Ok, I gotcha now.  Sounds like something's getting caught up in the
cache.

could provide the answer for them), in modules, I had to control the
opening and closings of a file (USROPN keyword on FSPECS).   If you have
the USROPN keyword on the display file, make sure that the display file
is being closed when you leave the service program.

If you try to compile a module without explicitly  controlling the
files, the module will compile, however, you will compile with severity
of 10 (well, that also depends on your compile level).
You will receive the following message in the compile listing...

*RNF7534 10      1 Files should be closed explicitly when NOMAIN is
specified
                   the Control specification.

If you go the route of controlling the opening and closing of the
display file... At service program begin...

If not %Open(DISPLAYFILE);
   Open DISPLAYFILE;
EndIf;

When Leaving...

If %Open(DISPLAYFILE);
   CLOSE DISPLAYFILE;
EndIf;
