BIT

To perform a BIT check, specify the check item TYPE as BIT. A BIT check allows you to verify that a variable contains only 0’s and 1’s.

Here is an example where a BIT check in the choices variable class ensures that specified variables are in BIT format:

<!doctype dm system>

<varclass name=choices type='CHAR 1'>
  <checkl msg=liba021>
     <checki type=bit>
  </checkl>
