I have just got a small relief, after working on complex program coding. Finally I have done it. There are some ISPF commands we need 24×7 to do coding well.
UNNUM ==> Replace line numbers with blanks. Turns off number mode.
PROF LOCK==> It locks profile
PROF UNLOCK==> We can edit profile
NUM ON STD COB==>To use line numbers as COB
NUM OFF==> To avoid line numbers in 73-80
NONUMBER==> It turns off number mode.
See still many here.
