What this means is that f-base can't find one of your functions, and since 
the function has the "()" after the keyword it's assuming it's a array 
instead of a function.

A word of caution here! Even thought the F-base dox say you can have procedure
names up to 10 chars long, only use 8 chars for your procedure names. I've 
been nailed by making calls to procedures with names that long and f-base
said that it either didn't exist (and gave the subscript problem) or got it 
confused with another function with the same first 8 chars. Feature or bug, 
I never use more than 8 chars for this reason.
