JCL Extensions

Describes JCL extensions as used with Enterprise Server.

Syntax:

//*MFE: {keyword=value}[...]

Syntax Rules:

//*MFE: must be coded in columns 1 through 7
Keywords must start in column 8 or after
All extension keywords begin with the % sign

General Rules:

Code each extension on a line following the last line of the entire JCL statement to which it applies.
All other JCL syntax rules apply.

Parameters:

keyword=value

Specify an extension keyword and value. All extension keywords must begin with the % (percent) character.

Example:

//STEP1    EXEC PGM=MYPROG,REGION=1024K,
//              ACCT=(‘ACCOUNT INFO’),
//              PARM=’parameter string’
//*MFE:         %TYPEXEC=HOST,%SOMEOTHER=SOMEVAL
//*MFE:         %ANOTHER=VAL

In this example, three extension keywords apply to the EXEC statement and follow the complete statement. %TYPEXEC, %SOMEOTHR, and %ANOTHER are extension keywords.
