Use this file-, record-, or field-level keyword to enhance the error checking performed against fields with the data type numeric only.
When specified on a numeric only field, this keyword causes an error message to be returned if the user attempts to embed a SPACE, PLUS SIGN or MINUS SIGN between numeric digits in the field or when the PLUS SIGN or MINUS SIGN precedes the numeric digits.
This keyword has no parameters.
The field containing the VALNUM keyword must be defined as an input-capable field with the data type Y.
Option indicators are not valid for this keyword.
The following example shows how to specify the VALNUM keyword:
|...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8 00010A R RECORD 00020A F1 5Y 0B 3 4VALNUM 00030A F2 5Y 0B 4 4
In this example, field F1 will not allow the user to embed a SPACE, the PLUS SIGN or MINUS SIGN within the numeric value or precede the numeric value with a PLUS SIGN or MINUS SIGN. Field F2 will be treated as described in the Data type/keyboard shift for display files (position 35) topic.
