One or more DBCS characters or a Shift Out (SO) character were specified in the TSO/E OMVS command ESCAPE operand. However, only SBCS characters may be used as escape characters. OMVS cannot use DBCS escape characters.
The OMVS command continues processing. None of the DBCS characters in the ESCAPE operand string are treated as escape characters. Any valid SBCS characters in the string are used as escape characters. The accepted escape characters appear at the bottom of the OMVS screen.
Make sure that any CLISTs or REXX EXECs that invoke OMVS do not specify DBCS characters in the TSO/E OMVS command ESCAPE operand.
Specify only SBCS characters in the OMVS command ESCAPE operand string. Do not specify any DBCS escape characters.
