Edit Reason: Said wrong character to print to clear screen

Wait, wrong computer LOL, on TRS-80 Model III had to clear the screen to get it away from "large" character mode, no wonder Family Computing Magazine and others were full of the "PRINT CHR$(147)" at one end and "CLS" at the other. Of course, that could be done with "WIDTH" in M$QB and descendants. The "CALL CLEAR" on Texas Instrument computer, however, was something I couldn't believe when I read about it a long time ago. Really, no button assigned to clear the screen? Maybe the screen didn't have that much to display anyway. Must have been even smaller than VIC-20 then.
Eventually I would like to create some equivalent functions in QB64 to run my old TI programs. The biggest challenge will be CALL SOUND!
Imagine small children being taught to program in BASIC and could just press a button labelled "CLEAR", or could even do a control-key combination to do it, but the selected few on a certain computer have to pretend it's COBOL.
EDIT 24 sept: not sure which character code was required printed for TRS-80, but the CHR$(147) was for Commodore 64. I'm sorry if I mislead anybody about this.
