To execute a CLIST, use the EXEC command.

From an ISPF command line, type TSO at the beginning of the command. In TSO/E EDIT or TEST mode, use the EXEC subcommand as you would use the EXEC command. (CLISTs executed under EDIT or TEST can issue only EDIT or TEST subcommands and CLIST statements, but you can use the END subcommand in a CLIST to end EDIT or TEST mode and allow the CLIST to issue TSO/E commands.)
