[Coco] [Color Computer] Question about BASIC coding guidelines

[Stan Mooney]

they are indeed stored as literal ASCII representations of the number
you can also increase the speed by converting statements like
       IF A=100 THEN GOTO 1000
                to
       IF A=100 THEN 1000

and
       IF A=150 THEN GOSUB 1200
                to
      IF A=150 GOSUB 1200

the GOTO is unneseccary in a "THEN GOTO" statement and
the THEN is unnecessary in a "THEN GOSUB" statement
(and, of course, all the spaces i put in the examples also waste time and memory--
but i included them to make them easier to read)

I know some BASICs tokenize the number (store it as a 16bit integer)

which makes the code smaller and faster (ok... if you don't get out of

single digit line numbers it might not be smaller).  I don't remember

what the CoCo does.
