hello IDL gurus: here's a fun self-referential problem that i REALLY need
solved. i have a lengthy minimization process coded using IDL. what i
would like is to allow the user to use my widgets to set minimization
parameters, etc. and then spawn idl as a UNIX process which runs the
minimization.
so i would use spawn to set the idl startup file:
spawn,'setenv IDL_STARTUP my_min_proc'
then, i would like to spawn idl as a unix process, using the unix 'at'
command:
spawn,'at now; idl; ^D'
the preceeding command starts idl using the specified startup file, but it
runs in the current terminal shell. if i exit the shell, i lose the
process.
any insight into this issue would be greatly appreciated!
thanks,
david mattes

spawn,'$IDL_DIR/bin/idl my_min_proc'
but now your terminal is taken over by the spawned process.
