TSO/ISPF Useful Commands: Entering and Running Your Program

Editing Files

Function Keys
- F2 - Split the screen where the cursor is (You then have two separate, independent screens for editing or viewing files or using the IOF. This is very useful for editing and viewing your errors at the same time)
- F3 - Exit (saves automatically if you are editing a file)
- F5 finds the next occurrence of phrase (see find below)
- F7 - Move up a screen
- F8 - Move down a screen
- F10 - Move screen to the left
- F11 - Move screen to the right
AT the COMMAND= =>prompt, type:
DOWN n - move down n lines
UP - move up n lines
SUB - to compile and run your program
IOF - to look at your output
F phrase - finds phrase. Use f = =>to find your first error when looking at your error listing.
Copy - bring up screen for copying another file into your file

In the editor and IOF, typing CSR and hitting enter in the top-right corner of the screen, to the right of Scroll ===>, makes F7 and F8 advances based on where the cursor is, rather than a whole screen at a time.

Copying and Moving Text in the Editor
A sample screen of moving follows the instruction.

Step 1: Marking Text
- a.Move to the first line you want to mark.
- b.Type over the line numbers on the left side of the screen:

Step 2:Inserting Text

IOF Commands

The IOF is where you view your output files. If you have many errors, you probably will want to split the screen so you can see errors and code at the same time. If you split the screen use IOF in the botton half of the screen and change and re-submit your code from the top half. Below is a short description of IOF commands. A more in-depth description of looking at your errors is available. To reach the IOF, type IOF at the command = = => from anywhere in ISPF

F phrase - finds phrase. Use f = = >to find your first error when looking at your error listing.

Using 4 as an example, at the command==> prompt, type

4 - look at item number 4 of menu on your screen.

4r - release number 4 to the printer and erase it.

4c - cancel (erase) item number 4 from the menu. 1-4c cancels items 1 through 4.
