Using a regular expression on the FIELD parameter

On the FIELD parameter, use the regular expression instead of a mask. A mask and a regular expression cannot both be specified on the same FIELD parameter. The maximum length of the regular expression is 250 bytes. The regular expression can be specified on a field based on a group trigger, a field based on a floating trigger, or a transaction field. Masks can be specified only on fields based on floating triggers and transaction fields.

ACIF extracts the text specified by the column and length values. The maximum length of a field that can be specified in the FIELD parameter is 250 bytes. After the field is extracted, ACIF applies the regular expression to the text. Any text that matches the regular expression is extracted for the field. If the matching text is shorter than the length specified in the FIELD parameter, it is padded with blanks until it equals the length.
