Code:

1
a. //Sysprint dd sysout = *
b. //Sysout dd sysout = *
c. //sysin dd data/*/dummy

[li] sysprint will list all messages pertaining to execution
[li] sysout the same

difference in the two is what files the program allocates. For IBM utilities u need to see the manuals.

in your case the * means it will be 'printed' to the quee inicated in the MSGCLASS parameter of your jobcard

[LI] sysin is control statements to be passed to utilities * means they follow in your jobstream
dummy means no file allocated to it

Code:

3. while using SORT utility,
if i give SORT FIELDS = NONE, SORT FIELDS = COPY. what happens?

sort fields = none eliminates duplicates while sort fields = copy will do a straightforward copy of your input dataset,

Is it SORT FIELDS=NONE or SUM FIELDS=NONE.
Second option will eleminated duplicate but in first case my guess is that it will give error. Please rectify me if wrong.

Sandip.

sandip,

my mistake SUM fields=none WILL eliminate dup.

SORT FIELDS=NONE may well end up in RC 16

why mop give it a try ?
