Thanks Alan and Gyle. My original post was at around 10am this morning (Sunday), according to my log, so not too early ;o)
I will try using the FILEINFO() function.

I don't have access to a system right now, but what about FILEINFO? It should return meaningful data for a file variable, and probably nothing for a non-file pointer. You could check that.

I can check if it is alpha, numeric, assigned and unassigned but I cannot find anywhere where I can determine a filevar type. My problem is that a routine is sent an Array to be saved to a file but the contents of that array are not known therefore I have to first convert any AM's in each array element (for the MATWRITE/MATREAD to work) but I have now come across a filevar in one of the elements - actually in 8 of them. Before anyone starts making comments like: "just don't allow it..." or "what "idiot" programs that way anyway..." etc.. I had better explain what I am doing and why I have the problem. I am converting System Builder and SB+ apps to mv4GL and one of the functions is to save the user's available common area to disk and restore them. Unfortunately the common variables can be used for any purpose and although there are specific variables designed for opening files, this particular app has opened them to a general PARAMS variable. In this latest conversion, so far every part of SB+ (except security) is converted 100% and the run-time executes 99.99% of the converted app - the only problem I have come across during my testing is this one. Sorry, this is sounding as though it is becoming an AD. Not my intention. Thanks for your help. Regards, Neil. -- Neil Charrington C.A.
