A BASIC declaration that allows explanatory remarks to be inserted in a program. It's suggested that you use ' to start your comments instead.

Syntax: REM remark
REM This is a comment, nothing is executed
' This is another comment, use this one in RapidQ rather than REM:

a=5 rem fkfkl,   - not working
a=5 ' fkfkl,   - works
