PACK ON/OFF

 

PACK ON/OFF 
 
Using PACK ON while editing and saving members in a dataset helps us 
utilize the space more efficiently. But Packed format is not supported 
while processing these members, say for example compiling a cobol program
in packed format may fail.
 
To save a member in Packed format you can give command line command
 
PACK ON
 
and then save the member 
 
To unpack the member you can edit the member and issue command line command
 
PACK OFF 
 
and save it to unpack it.
 
 
You can know which format your member is saved in by issuing the command line
command
 
PROF
 
which will list various other information including the format in which your member 
is saved.
