HI,
I have a flat (PS) file having 'n' number of records.each record is a dataset name. instead of checking the dataset existance for each record in the file using option 3.4, i need to know how we can do in REXX with a single job?

Read the list of datasets. For each dataset name, use the SYSDSN function to determine the status. For each dataset name that doesn't return an "OK", then take whatever action you wish.

Here is another way way in case you're interested:

dataset_exists:
/*-----------------------------------
arg dataset
x = LISTDSI(dataset 'RECALL')
if x = 0 then
return 1
else
return 0
