MSIR.0167 SYBMSG(137,15,1) Must declare variable '(varname)'.

This message indicates that varname was used as a parameter on an EXEC statement but had not been declared in a stream being handled by EXEC2RPC processing on a Janus Open Server port. This is indicative of an error in the client code. Turning on language/RPC debugging with a "JANUS TRACE 3" command and re-running the request will send the data being sent by the client to the Model 204 audit trail.
