SEQ1

The SEQ1 option specifies the beginning sequence number for each new member or job in the output stream.

This option has the following format:

SEQ1=number

number: Specifies that sequencing restarts with the specified number at a logical break in the original JCL. The default is 10.

Usage notes:

To prevent the generation of sequence numbers, code SEQ1=0. Any other value for SEQ1 results in the generation of sequence numbers in Columns 73-80.
Specifying SEQ1=0 also causes the clearing (blanks) of existing sequence numbers in columns 73-80. It is similar to the ISPF UNNUM option.
If the ISPF NUM ON option is in effect for the members JCLNeat is processing, ISPF overrides JCLNeat and generates sequence numbers regardless of the setting of the SEQ1 option.
