$PREFIX

$PREFIX GroupPrefix

The $PREFIX command defines the prefix for the fields in a group.

GroupPrefix is part of the COBOL variable name for each field. For example, if the group prefix is G1- and the field name, as defined in $FIELDS, is DATE, the field name is G1-DATE. GroupPrefix can be up to ten characters long and must be unique in a program ($PROGRAM). The last character of GroupPrefix should be a hyphen (-).
