Entering commands and parameters

When ACF/TAP starts, the following messages appear on the operator’s console:

DSJ001I ACFTAP EXECUTION BEGINS
DSJ021I PARAMETERS ARE RESET TO DEFAULT STATUS
DSJ020A ENTER ACFTAP PARAMETERS OR READ, QUIT, LIST, GO, RESET

In response to these messages, enter reply xx,command or reply xx,parameter=value. Where the following values have these meanings:

xx: Is the MVS™ system reply ID.
command: Is a valid ACF/TAP command.
parameter = value: Is a valid ACF/TAP parameter and value.

For more information about commands, see ACF/TAP commands. For more information about parameters, see ACF/TAP parameters.

If a READ command is entered, ACF/TAP runs the commands and parameters listed in the SYSIN data set. However, it is not necessary to enter the READ command from the operator’s console before the SYSIN statement can be read. After the JCL is read or entered from the console, enter the GO and QUIT commands. You can enter these commands from the console or inserted in the JCL. If the QUIT command is entered immediately following the GO command, in the SYSIN data set, ACF/TAP does not prompt the system operator.

After each entry from the operator’s console, ACF/TAP responds with the following messages:

DSJ020A ENTER ACFTAP PARAMETERS OR READ, QUIT, LIST, GO, RESET
DSJ029I message text shows the entry from the console.

If you make a syntax error while entering parameters, message DSJ029I is followed by message DSJ028I.

The vertical indicator (|) points to the approximate location in message DSJ029I where ACF/TAP stopped scanning the entry because of a syntax error. However, if the parameters are read from the SYSIN data set and a syntax error is detected, message DSJ089I prints in place of message DSJ029I.
