IDL Save file query routine [message #24839] Thu, 26 April 2001 10:08

IDL (I'm still using 5.3) has nice query routines to let you know if the
image read operation you are about to perform is likely to work.

Is there any way to query an IDL save file?
I want to idiot-proof a program which will restore
a save file that a user selects, but if the program tries
to restore file which is not an IDL save file, it will halt.

Is there a way to test?
