Specifying Files on Mainframe Systems

Mainframe file names can be up to 55 characters in any of the following formats:

• <tag> DD:ddname
• <tag> DD:ddname(member)
• <tag> 'qualifier.qualifier.qualifier'
• <tag> 'qualifier.qualifier.qualifier(member)'

Where:

• ddname is the data definition of the file in your JCL
• member is the member name of a PDS
• qualifier is a node of a data set

Alternatively, mainframe file names can be specified in this format:

<tag> JES:DD:ddname

Where ddname is the data definition of the file in your JCL. To access the JES2 spool use <FILE> JES:DD:ddname. The ddname contains one record to identify the spool file in the following comma-delimited format:

JobNumber,JobName,StepName,ProcName,DDName

Where:

• JobNumber is the job that created the JES file
• JobName is the name of the job that created the JES file
• StepName is the name of the job step that created the JES file
• ProcName is the name of the procedure used, if applicable
• DDName is the name of the DD that specifies the JES file

You can omit ProcName by placing two commas after StepName.
