The SEQ1, SEQ2 and NEW1 parameters (with the exception of SEQ1=ALL) specify eight (maximum) alphanumeric characters. The INCR parameter specifies eight (maximum) numeric characters. Only the significant part of a numeric sequence number need be coded; for example, SEQ1=00000010 can be shortened to SEQ1=10. If, however, the numbers are alphanumeric, the alphabetic characters must be specified; for example, SEQ1=00ABC010 can be shortened to SEQ1=ABC010.
