Using Aliases for Utility Names

Aliases, which are alternate names for the original IBM utility names, can be optionally defined in the CTJALUT member in the Control-M JCL Verify PARM library. When an alias is defined, Control-M JCL Verify processes the input SYSIN statements with the alternate utility name in the same manner as it processes the input statements with the original name.

Since there is no limit to the number of alternate names each utility can have, several aliases can be defined for the same utility name.

Duplicate contradicting definitions for the same alternate names are ignored.

Appropriate messages are issued indicating invalid definition lines. These lines are ignored and the processing continues.

After making changes to the CTJALUT member, the user must issue a “MODIFY ctj_monitor,REFRESH=ALL” command for the changes to take effect.

The format of definition has the following syntax:

  • Each line in the member defines one alias or comment.

  • The original utility name on column 1 (up to 8 characters)

  • Followed by at least one blank

  • The alternate (alias) name (up to 8 characters)

  • Followed by at least one blank

  • Comment (free text)

  • Asterisk in column 1 makes the entire line a comment.

For example, the following alias is defined in the CTJALUT member:

Copy 
IEBGENER  MYGEN1    MYGEN1 is an alias for IEBGENER

The following is the original JCL to be verified:

Copy 
//COPYFILE  EXEC  PGM=MYGEN1                                        
//SYSPRINT  DD    SYSOUT=*                                           
//SYSUT1    DD    DISP=SHR,DSN=QUEST.JVER.ACCESS($README) 
//SYSUT2    DD    DISP=MOD,DSN=QUEST.JVER.ACCESS($README1)               
//SYSIN     DD    DUMMY                                              

The following is the result of the verification:

Copy 
//COPYFILE  EXEC  PGM=MYGEN1

//SYSUT2    DD    DISP=MOD,DSN=QUEST.JVER.ACCESS($README1)                  
//SYSIN     DD    DUMMY
