TP Editor

I hear you there........

Have a look at Section 5 (Monitor Commands) in the AS Language Manual for PRINT.
You will see many 'format specification codes' which you can apply to the Print command to allow specified formats to be displayed.
Not too sure if there is a 'global clear screen command' so I utilize the /Cn specification for line feeds and basically print an empty message per line.

ie PRINT /C50," "; This will automatically print empty message on the next 50 lines just by the single command.

Hope it helps......................

Lol......in that case here's a 'bonus' you may not be aware of.....

You could also create something that is called an alias.
- Where you map an AS command/instruction to a name of your choosing to execute in the terminal editor window.

ie say you wanted to use a word like cls as used in DOS to clear the screen.

In the terminal enter:
zalias cls = PRINT/C50," "

This creates the alias.
All you would need to type in to execute that command would be cls and enter in the terminal editor window (inc Teach Pendant Keyboard).
The alias is stored in a full file save in the SYSDATA under zalias.
To return a list of stored zalias just type in zalias and enter......and you will see ALL zalias currently stored if any.

Give it a go................

I concur. I do not think that there is any global clear screen command.
The method I used with V+ language which is very similar to AS is:

PRINT /C25, /U25 ;insert 25 carriage returns, then move cursor UP 25 lines (clears page, returns cursor to top)

I cannot remember if AS supports the /U modifier, not sure that it does.

I looked at an old program to see how it was done, here is the code snippet.

; called from main()
;
; clear the screen 25 lines
  PRINT /C25
;
; initialize the variables
  $choice = ""
 
;print the menu structure text
  PRINT /X15,"MAIN OPERATOR MENU"
  PRINT /C1,/X10,"S        RUN STRAIGHT"
  PRINT /C1,/X10,"A        RUN ANGLE"
  PRINT /C1,/X10,"X        EXIT THE PROGRAM"
  PROMPT "               ENTER THE LETTER OF YOUR CHOICE ==>   ",$choice 
;

So it appears that I found no means of accomplishing the /U functionality using AS.
