CPSC 3121 Assembly Language Programming
Spring 2008 Lab 3 Due Friday, March 21, 2008
The purpose of this lab is to run the previous lab, this time with output to a named disk file,
rather than to the standard output viewed in the hold queue.
There is only one change that is required to the previous lab assignment in order
to provide output to a named disk file.
The line to be replaced occurs near the end of the job stream. It is
//GO PRINTER DD SYSOUT=*
Running with Output to Disk
To output to file SP2008.LAB1OUT in your user area, replace the GO.PRINTER line with
//GO PRINTER DD DSN=KCNNNNN.SP2008.LAB10UT,SPACE=(TRK,(1,1),RLSE),
// DISP=(NEW,CATLG,DELETE)
Neither the name “SP2008” nor the name “LAB1OUT” can exceed eight characters in length.
Don’t forget to place the comma at the end of the line.
Don’t forget to change “KCNNNNN” to your own user ID.
Viewing the Output Disk File
From the main menu, enter the four character string “=3.4” and hit ENTER twice.
Find the output file by using the F7 and F8 keys as well as the TAB key.
There are two ways to examine this file.
S Place S by the file name and hit ENTER.
This will show the file attributes, but not the text of the file.
E Place E by the file name and hit ENTER twice.
The text of the file should display.
