Is there a way to find out if a field exists in a record using indirection? Something like:

if exist {pFilename + ".GUID"} .....

If can file if exists for files etc. but not a field name. I am sure there is and I am just missing it.

Thx

john

The only way i know is searching in the result of the HListItem function

Hi John,

I find this Help page useful:

John,

If you must use indirection then I suppose you could test for field existence by trying to use the field (using indirection syntax) and doing so within an exception trap construct. Then if the exception triggers you know the field does not exist otherwise, if no error, then it does.
