Next without For

[CharlieJV]

Is this a bug or a feature?

It keeps displaying 0 continuously..

Should it say 'Next without for'??

Code: (Select All)

10 GoTo 30
20 For l = 1 To 10
  30 Print l;
40 Next
50 End

With the interpreted GW-BASIC, it gives that "Next without for" error, which makes sense.  Being interpreted, going from line 10 to line 30, the program has no idea there is a For loop going on at line 20.

QB64, though, is a compiled BASIC.  The BASIC gets transpiled to C++ before being compiled to an EXE.  We would need to dissect the C++ code to see what the compiled program is doing.

Just for the giggles, here is what BAM does:
