[Gambas-user] R: Unending cycle "For...Next" with variable As Byte

[RICHARD WALKER]

Problem with that is that the second "Print ii" statement is executed,
even if the loop is skipped (because of initial conditions). The
SuperBASIC version would print nothing if the initial loop conditions
indicate it should be skipped

The Gambas equivalent would be more like

For ii = 0 to 254
    Print ii
Next
If (some test by which we can tell the loop has iterated at least once) Then
 Print ii
End If

Also, an EXIT statement in the loop would leave the SuperBASIC FOR
loop, skipping the loop epilogue (the bit between the NEXT and the END
FOR).

A better trivial example of the loop epilogue in action might be:

FOR character = 1 to LEN$(test$)
       IF test$(character) == "@" THEN EXIT character
NEXT character
       REMark Character not found
       character = 0
END FOR character

IF character THEN
       PRINT test$(1 TO character-1) & test$(character+1 TO )
ELSE
       PRINT "Not found"
END IF
