RE: Problem using CHECK

Have you considered replacing with scan?  (assuming you are using ILE)

The SCAN operation scans a string (base string) contained in factor 2 for a
substring (compare string) contained in factor 1. The
scan begins at a specified location contained in factor 2 and continues for
the length of the compare string which is specified in
factor 1. The compare string and base string must both be of the same type,
either both character, both graphic, or both UCS-2.

Factor 1 must contain either the compare string or the compare string,
followed by a colon, followed by the length. The compare
string portion of factor 1 can contain one of: a field name, array element,
named constant, data structure name, literal, or table name.
The length portion must be numeric with no decimal positions and can
contain one of: a named constant, array element, field name,
literal, or table name. If no length is specified, it is that of the
compare string.

Factor 2 must contain either the base string or the base string, followed
by a colon, followed by the start location of the SCAN. The
base string portion of factor 2 can contain one of: a field name, array
element, named constant, data structure name, literal, or table
name. The start location portion of factor 2 must be numeric with no
decimal positions and can be a named constant, array element,
field name, literal, or table name. If graphic or UCS-2 strings are used,
the start position and length are measured in double bytes. If no
start location is specified, a value of 1 is used.

The result field contains the numeric value of the leftmost position of the
compare string in the base string, if found. It must be numeric
with no decimal positions and can contain one of: a field name, array
element, array name, or table name. The result field is set to 0 if
the string is not found. If the result field contains an array, each
occurrence of the compare string is placed in the array with the
leftmost occurrence in element 1. The array elements following the element
containing the rightmost occurrence are all zero. The
result array should be as large as the field length of the base string
specified in factor 2.
