Dear David,
Thanks for the input. Let me write what I understand of the program
I am trying to work with.
I have a seperate program, setup.pro that does not require any input
from the user & there are no widgets. The program is usually run using
a macro that runs a batch file
@bathfilename.pro --
ON_ERROR,1
;run setup - Uses DEFSYS to define system variables
[DEFSYSV,"!MY_dir",basedir + libdir (basedir & libdir are defined)]
SETUP
;run xmanager
XMANAGER
;run main - uses the system variables that have be defined in
setup.pro
MAIN
- When I try to run the macro- it works fine
- When I run all these in the command prompt, it works fine
- To do a standalone application, I executed all these commands in the
command prompt as follows
on_error,1
.run setup
setup
.run xmanager
.run main
resolve_all
save,/routines, filename = "filename.sav"
When I run the .sav file, I get an error - '!MY_dir is not a legal
system variable'
Please Help,
Thanks,
-HJ
