Hi,
Is there any way to read a Tape data set directly from rexx using
EXECIO? If the Tape data set has 10 million records can we directly read
the Tape data set?



Thanks,
Krishna

Yes you could, however you may not be able to read in all records at once, using an asterisk (*) in the lines parameter field of the EXECIO command, due to probable memory limitations.

Furthermore you would also have (I might be wrong here) to run the Rexx in batch as you would not get the tape mounted when running in foreground.

Otherwise, there is no apparent difference when reading a tape as opposed to when reading a DASD based dataset.
