Edit Macro JDSN - JCL Dataset Name

       Disclosed is an external tool to help programmers any
dataset name errors of JCL statements prior to the jobs in the
production environment, or moving into the test environment.

      Currently, programmers cannot submit a production batch to
check new sets of JCL statements or changed JCL for errors.  Usually,
programmers have to check and then wait until the job runs in the
next or use the following methods:

      Under a JES2, or JES3 (Job Entry Subsystem) environment, can
check JCL syntax errors by "TYPRUN=SCAN" in the job  "TYPRUN=" is an
optional parameter in the job card. a "SCAN" subparameter in the
"TYPRUN=" will request the system scan JCL for syntax errors, without
the job or allocating devices.  This parameter the system to check
for:  invalid keywords; invalid parentheses errors; parameter value
errors or parameters in a JES3 system, but not in a JES2 invalid
syntax on JCL statements in cataloged invoked by EXEC statements in
the job.

      However, the system does not check for misplaced

      Under the JES3 environment, we have another method to JCL in
addition to the TYPRUN=SCAN parameter on the JOB  JES3 programmers
can code PGM=JCLTEST or on the EXEC statements.  This causes the
system scan the JCL for syntax errors or excessive parameters
processing the job or setting up devices.

      Programmers may use above methods to debug the syntax the JCL
statements.  However, the statu...
