Common Issues

"Syntax Error"

Check your BASIC syntax: - Line numbers must be first - Commands must be valid BASIC keywords - Strings need quotes

See: BASIC Language Reference

"Runtime Error"

Program has a logic error: - Division by zero - Invalid GOTO target - Type mismatch

Error message shows line number where error occurred.

No Output

Check if: - Program has PRINT statements - Program reached those statements - Program didn't hit an error first
