Commodore 64 User Manual page 159

Commodore 64 BASIC would interpret the second equal sign as a
logical operator and set B = -1 if C = 0. Instead, convert this state-
ment to:
10 C=0 : B=O
Multiple Statements
Some BASICs use a backslash (\) to separate multiple statements on
a line. With Commodore 64 BASIC, separate all statements by a colon
(:)•
MAT Functions
Programs using the MAT functions available on some BASICs must be
rewritten using FOR. . . NEXT loops to execute properly.
