If you need to use characters other than the defaults for REXX's OR, NOT and CONCAT operators, MSS enables you to do this using three environment variables: MFREXX_OR, MFREXX_NOT and MFREXX_CONCAT. You must set these environment variables before you start the enterprise server for them to take effect, either in the Configuration Information field on the Add Server or Edit Server pages of ES Admin or on the command line.
You can specify one or more characters for each operator, and each character you specify is used in addition to the default operator; that is "|" for OR, "¬" for NOT and "||" for CONCAT. When specifying additional characters, you must ensure that each additional character is defined in single or double quotes, or in hexadecimal. When specifying more than one character, separate each one with a space or comma. Any error in the specification of the additional characters, including the specification of alphabetic or numeric characters, results in the environment variable being ignored.
