NUM

To perform a NUM check, specify the check item TYPE attribute as NUM. A NUM check allows you to verify a variable as a numeric character 0-9.

Here is an example where a NUM check in the numbers variable class ensures that specified variables are numeric:

<!doctype dm system>

<varclass name=numbers type='CHAR 5'>
  <checkl msg=liba022>
     <checki type=num>
  </checkl>
