About Comments
Adding comments to your GCBASIC program can be done using a number of methods. Explanatory notes embedded within the code. Comments are used to remind yourself and to inform others about the function of your program. Comments are ignored by the compiler
You can comment out sections of code if you want just by placing an apostrophe at
the beginning of each line. The GCBASIC IDE has a feature to do this automatically.
You can also use a REM (for REMark statement), a semi-colon or two forward slashes.
Multiline comments are support for large text descriptions of code or to comment out chunks of code while debugging applications.
Syntax:
/*
block comment
*/Warning: Graphical GCBASIC uses semi-colons to mark comments that it has inserted automatically. It does not read these comments when opening a file, so any comments in a GCBASIC program starting with a semi-colon will be deleted if the program is opened using Graphical GCBASIC.
Example:
' The number of pins to flash
#define FlashPins 2
REM You can create a header using an apostrophe before each line
REM This is a great way to describe your program
REM You can also use it to describe the hardware connections.
' You can place comments above the command or on the same line
Dir PORTB Out ' Initialise PORTB to all Outputs
; The Main loop
do
PORTB = 0 ' All Pins off
Wait 1 S ' Delay 1 second
PORTB = 0xFF ' All pins on
Wait 1 s ' Delay 1 second
Loop
