Reserved Character/BASIC Program, Releases: AP and R83

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.

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.

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.
