CN(INTERNAL)
the info tells that the message was routed to the <INTERNAL> console, not that the jcl had an internal error
The message shown refers to job PRAK040A the job shown is prak040m.
since the jcl and the submit command do not understand lower case
the ts was asked to enter the jobname characters ( the suffix to be appended to the userid )
the JOB card was probably built correctly, but the rest was still lowercase and hence the JCL error
it is not likely that the program that processes the statement in the data set specified by the DD statement with DD name SYSUT1 will accept lower case characters.
dfhmaps is the procedure to <prepare> a cics bms maps ( the assembler will be happy to process statements in lower case )
the procedure is likely to contain four steps
one - iebgener to create a sequential dataset with the source
two - assembler to create a dsect ( invoked with SYSPARM(DSECT) - IIRC )
three - assembler to create the map ( invoked with SYSPARM(MAP) - IIRC )
four - binder to link the map
