Tips & Tricks

Get the most out of the MBASIC Tkinter GUI.

Note: Some features described below (Smart Insert, Variables Window, Execution Stack) are documented here based on the Tk UI design specifications. Check Settings for current implementation status or refer to the actual UI to verify which features are currently available.

Smart Insert for Rapid Development

Scenario: You have a skeleton and need to flesh it out:

10 REM Initialize
100 REM Process
200 REM Output
300 END

Use {{kbd:smart_insert:tk}} (Smart Insert) to insert blank lines under each section without calculating line numbers!

Variables Window for Arrays

When working with arrays, keep Variables window open ({{kbd:toggle_variables:tk}}):

10 DIM Scores(5)
20 FOR I = 1 TO 5
30   INPUT "Score"; Scores(I)
40 NEXT I

Watch each array element fill in real-time!

Execution Stack for Nested Loops

Press {{kbd:toggle_stack:tk}} (Toggle Stack) while stepping through nested loops to see the current state of all active loops.

Quick Testing Cycle

Fastest workflow:

Type → {{kbd:run_program:tk}} (Run) → Check → Edit → {{kbd:run_program:tk}} (Run) → Check → ...

No need to save between test runs! Save with {{kbd:file_save:tk}} only when satisfied.

Use Comments Liberally

MBASIC supports two comment styles:

10 REM This is a remark statement
20 ' This is also a comment (shorter!)

Add comments with {{kbd:smart_insert:tk}} (Smart Insert).

Common Mistakes to Avoid

Manually calculating line numbers → Use {{kbd:smart_insert:tk}} (Smart Insert) ❌ Running without saving → Save often with {{kbd:file_save:tk}}Ignoring ? markers → Fix syntax errors before running ❌ Not using Variables window → You're debugging blind! ❌ Stepping through entire program → Use breakpoints + Continue (Run menu)

Renumber Before Sharing

Keep development line numbers messy, but Renumber ({{kbd:renumber:tk}}) before sharing code. Makes it clean and professional.
