REM or an apostrophe is used for programmer remarks, comments or to stop the execution of program code.
Syntax
- REM program comment or ignore code
Description
- Comments cannot be read by Qbasic correctly and may cause syntax and other errors without REM!
- Instead of REM you can use the Template:KW symbol which can be put anywhere.
- Code can also be commented out for program testing purposes.
- Qbasic Metacommands such as Template:KW and Template:KW require the use of REM or the apostrophe.
Example: Avoiding an END IF error.
REM This is a remark... ' This is also a remark... IF a = 0 THEN REM (REM follows syntax rules) IF a = 0 THEN '(apostrophe doesn't follow syntax rules, so use END IF after this) END IF |
