TUNE0006 Invalid (cmd) parameter - (parm).

This indicates that an invalid parameter was found for a statement in SIRTUNEI or for a command issued via SMSG or MODIFY. If the error was in SIRTUNEI, the line with the invalid statement is echoed before this message, and SirTune will not come up. In this case, SIRTUNEI must be corrected before the ONLINE, or BATCH204 job will come up.

The correct format of the statement or command can be found in Refer to the /tunr.pdf SirTune Reference Manual.
