The () (left and right parentheses) reserved characters surround arguments within functions, encloses subscript references within dimensioned arrays, and override the normal order of precedence evaluation.
|
NOTE |
For every (, there must be an associated ). |
Example(s)
() 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.
