Editing TI-BASIC (section)

=== Comments ===
==== TI-83/84 (Z80) ====
Z80 programmers often start lines with " (double quotation mark) to denote a comment. Lines starting with " are actually executed changing the <code>Ans</code> variable, but this does not affect anything other than performance unless <code>Ans</code> is read immediately afterwards.

==== TI-89 (68k) ====
The 68k calculators allow programs to include single-line [[comment (computer programming)|comments]], using [[copyright symbol|©]] as a comment symbol.  If a comment appears as the first line after the "Prgm" statement, it is displayed in the status bar when the program is selected in the catalog; such comments are often used to document the names or types of parameters.  The 68k interpreter has a built in feature to store the number of space characters at the beginning of a line, this allows [[Indentation style|indentation]].
