DNUMIN Procedure
<14> Disallow prefixes (%, #, and so on)

If not supplied,
flags defaults to zero.
Considerations
•
Number conversion stops on the first ASCII character that either does not
represent any numeric value or that represents a numeric value greater than (
base
-1). For bases greater than 10, where letters are used to represent the values 10
and above, both uppercase and lowercase letters are accepted. Embedded
commas are not allowed.
•
Decimal numeric values must be in the range -2,147,483,648 to +2,147,483,647.
•
Numeric values in other number bases must be in the range -%h80000000 to
+%hFFFFFFFF. DNUMIN accepts positive numbers in the 32-bit range and
negative numbers in the 31-bit range.
Example
STRING .number[0:15] := ["-2147483640 "];
INT(32) result;
INT base := 10;
INT status := 0;
.
.
CALL DNUMIN ( number, result, base, status );
IF status <> 0 THEN ...
