I don't know the answer to your question, but can you post the the line of logic you used?

[I'm trying to get more info on how to use SYSF as it is an undocumented logic command. I'll test your syntax here to see if I get the same result.]

To Create

SYSF( &#@CREATE, $file_name, key_length, record_length )

To Delete

SYSF( &#@DELETE, $file_name )

To Check if file exists (useful befroe delete )

SYSF( &#@CHKFILE , $file_name , #A )
#A is Zero if file exists.

Hope this helps.

I'm suspicious that the ERROR OPENING FILE message came from a PRO-IV attempt to read the file. Where in the function did you run the SYSF command? Are you trying to delete a file that's actually used in the function?
