TAA Tools

The EXCCMD  command executes one  or more commands  stored in a  source
member.   The command is helpful  when you want to execute  a stream of
commands  without submitting the  commands to batch.   The commands are
executed synchronously.    This  means  the EXCCMD  will  not  complete
until all commands in the source member are executed.

The commands  in the source member must  not have a JOB,  PGM or ENDPGM
command.   The  commands should  be entered  by SEU  or written  to the
source member by a HLL  program or by a  function such as the TAA  Tool

EXCCMD can also be  executed from a HLL program to execute  a series of
stored  CL  commands.   The  default  source file  for  the  command is

A typical command would look like:


The member  CLCMDS  in  the  file QCLSRC  would  be  accessed  and  the
commands within the member would be executed.

A typical  use  of EXCCMD  is in  conjunction with  TAA Tool  CPYJOBLOG
command.   For example,  assume you have  entered a series  of commands
using  the  command entry  display and  now need  to execute  the exact
same  series  of  commands.    Rather  than  duplicating  each  of  the
commands, you could:

  **   Use CPYJOBLOG to copy the commands to a source file member

  **   Edit the commands with SEU

  **   Execute the commands with EXCCMD

The EXCCMD command  operates on any source file  that can be maintained
by  SEU (240  byte  maximum).   Commands can  be  longer than  a single
source statement  assuming the proper  + or  - ending  symbol is  used.
Comments can exist in the source.

A  parameter exists  to determine  what to  do  if errors  exist.   The
default is  to abort which causes all commands  to be executed and then
EXCMD ends with  an escape  message if  any errors occurred.   You  can
request to end  immediately on the  first error or request  that errors
be bypassed.

Command parameters                                    *CMD

   MBR           The  member name which  contains the  CL source  to be
                 executed.   If  the member  does not  exist, an escape
                 message will occur.

   SRCFILE       The  qualified  source  file  name.    The  file  name
                 defaults   to  QCLSRC  and   the  library   to  *LIBL.
                 *CURLIB may also be specified.

   CMDERR        Determines  what  to do  on  command errors  or  if no
                 commands exist to be executed.

                 *ABORT is the  default and  causes the EXCCMD  command
                 to send  an escape  message if a  command fails.   The
                 escape  message which caused  the error  is resent for
                 the command being executed.   If no commands exist  to
                 be executed,  CPF9898 is  sent as  an escape  message.
                 *ABORT  does  not  cause  EXCCMD  to  send  an  escape
                 message until all commands have been executed.

                 *ABORT2  causes EXCCMD  to send  an escape  message on
                 the first command that fails.

                 If  *BYPASS  is specified,  the  EXCCMD  command  will
                 successfully  execute  and  will return  a  completion
                 message   regardless   of   whether   command   errors
                 occurred or any commands existed.

                 If a  completion  message is  sent,  the text  of  the
                 completion message  will differ  depending on  whether
                 errors were found or no commands existed.

                 If  *NOCMDS is  specified, an  escape message  will be
                 sent if a command fails,  but a completion message  is
                 sent if no commands exist to be executed.

   PRTSRC        Determines if the source member should be printed.

                 *NO is the default to not print the member.

                 *YES may be specified to always print the member.

                 *ERROR may  be specified to  print the member  only if
                 a command in the source has failed.


A command  up to approximately  5,000 bytes in length  may be executed.
