Applicable release versions: AP, R83
Category BASIC Program (486)
Description used to surround arguments within functions, or to enclose subscript refererences within dimensioned arrays. It is also used to override the normal order of precedence evaluation.
Syntax
Options
Example
"(" as a function delimiter:

if not(num(response)) then crt "must be numeric!"

As a dimensioned array reference:

if cust.array(22) = "" then cust.array(22) = "hold"

Changing precedence in an arithmetic expression:

age = (today - birthday) / "365" 

Without grouping precedence, the above calculation produces an inaccurate 
result due to the fact that division occurs at a higher level of precedence 
than subtraction.
