NetMaster REXX Environment › EXECIO

EXECIO

NetMaster REXX uses the EXECIO command to read and write data to or from a file. You can use EXECIO to do the following:

• Read from a data set to the REXX data stack for serialized processing, or to a list of variables for random processing.
• Write data to a data set from the REXX data stack or a list of variables.

EXECIO emulates the TSO/E EXECIO command with the following exceptions:

• DISKRU

  DISKRU is not supported.

• DISKW (empty stack for non 3270 session)

  If an EXECIO * DISKW command is issued from a non-3270 type session and the REXX data stack becomes empty before a null record is found (which would normally terminate EXECIO), then the EXECIO request completes normally instead of requesting input from an arbitrary input data stream (because there is no equivalent for SYSTSIN DD in CA NetMaster).

• Return Code 4 is not used

  TSO/E EXECIO terminates with a return code of 4 when an empty data set is found within a concatenation list during a DISKR operation. NetMaster REXX EXECIO does not have that restriction.

Note: for more information about EXECIO, see your IBM TSO/E documentation.
