Thanks for the great replies:
To recap, it seems like there are two steps that I need to get a grasp
of (followed by what I am begining to understand from responses - bear
with me, I'm a total newbie) -
1. Identify whether the file I want to use in IDL is being used by
another program.
2. If it is in fact being used, identify the process using it and kill
it
With regard to 1. Unfortunately, I can't use the SPAWN PID keyword to
identify the process because I'm actually spawning a windows BAT file
that in turn spawns the EML script. So the PID will identify the BAT
process, which finishes in less than one second. Also, the File_test
read/write keywords, from what I can tell, identify whether you have
read/write permissions within that directory (am I wrong? In any case,
the keywords are telling me that I can read/write a file that is being
used by another process). SO... I'm beginning to think that I need to
get a better grasp of IDL error handling functions. Can I just have IDL
report/catch/capture the error (when it tries to move a file that it
can't) and move on to the next line withouth going back to interactive
mode?
With regard to 2. It seems that killing an app can't be done through
IDL but could be done through vb. Rick, thanks for the info, and thanks
for giving me something to do over the weekend because I don't know ANY
vb...
Thanks helpful people...
