Description:

Throughout the Processing_tables Reference section, you will see "exp" or "expression". This means any legal filePro code that will eventually resolve to a number, date, time, or string-of-characters. Loosely translated, an expression is anything that can go on the right side of an equals sign on a "then" line.

Examples:

4
Z
Aa
3/"2"
3/aa
mid(@td,"1","2") & "/" & mid(4,"4","2") & "/" & mid(9,"7","2")
filename(n) This type of expression has some limitations when used in manyplaces where expressions would normally work.
