└──────────────┘
1) LF.CLA - main program that calls the display procedure
2) DISPFILE.CLA - procedure to actually display file to monitor
Compile both programs. All 'LF.CLA' does is call the actual DISPFILE procedure.
You can change 'DISPFILE.CLA' to be a standalone procedure that any program can
call. All you need to do is modify the MEMBER statement in 'DISPFILE.CLA'. You
need to set a Global variable(DISFNAME) to the name of the file to be displayed
before calling the DISPFILE procedure(or make DISPFILE into a function).

│Split Screens │
└──────────────┘
The screen may be split vertically, horizontally, or both. The F7/F8 keys
will toggle the splitting on or off. To split the screen, press the function
key, then use the arrow keys to mark the area you want to split or "lock", then
press the <ENTER> key to set the split. The file movement keys then allow you
to move the "unsplit" part of the screen as before. Press the function key
again to remove the split screen display.
Splitting the screen vertically is useful for displaying files larger than 80
columns. Split the screen vertically (F7), then use the left/right arrow keys
to show the rightmost columns of the file.
