Should place cursor using VT52 escape sequences #11

Closed hackerb9 closed 2 years ago

hackerb9 commented 2 years ago

The Tandy computers use PRINT@ while the NEC computers use LOCATE. However, both of them understand VT52 style escape sequences to position the cursor. It's a little more complicated but is something like: 

PRINT CHR$(27) + "Y" + CHR$(32+row) + CHR$(32+column)

Yes, that's it! I couldn't remember the difference but yeah, something like that may harmonize the code.

According to https://www.web8201.net/xcompat.asp, M100LE should use the following subroutine:

50000 PRINTCHR$(27)"Y"CHR$(32+Y)CHR$(32+X);:RETURN

Usage:

100 X=5:Y=2:GOSUB50000:PRINT"Isn't that simple?"

I suggest using variable names less likely to collide in the future. Perhaps PX and PY?

Yep, that looks like it'll do the trick. And yeah, I'm going to have to do a full walkthrough of this code again. It's been too long since I really 'knew' it... life getting in the way.

Marked as enhancement as it'll ease cross-coding to NEC and other m100 siblings.
