handling errors while reading in data files [message #1352]

Hi, I'm trying to write an application using IDL that, among
other things, reads in a user specified data file. These files have to
be of a specified format to be read in correctly. Now we all know users
make mistakes and will sometimes specify files that are not of the
correct format. Now if this sort of thing happens, while running the
application I'm writing, eventually some sort of read error will be
generated by a READF or RMF statement, the result of which is that my
program crashes. This is unacceptable. I need a way to be able to handle
errors created by reading in files that are of the wrong format.
I was able to figure out how to handle the case when a file doesn't
exist, but not when it is of the wrong format. Does anyone have a
solution to this problem. Any help would be greatly appreciated.
Please email me any suggestions you might have.

Thanks in advance.
