For...Next Step Variable

[blueznl]

oh, i think it's something that a decent basic should have, so it's definitely a wish list item, but it's not very important compared with all the other things on my wishlist

hey, it's not important IF other languages have it, only if it makes sense to have it (and for cross language comparisons, and easy porting it's nice to have it)

I think a step-variable is a good idea and I need it
also for my program.

@Fred: I hope you put the 'Step variable' on your 'To Do' list. Also users on german forum are requesting this (here)

[plaxor]

gonna bump this thread even if its old..

why 'Step variable' is not implemented?

[Dude]

I take good notes.

It's now 2018.

2019, soon 2020 ...

While the trick with 0 step and manual incrementing/decrementing of the variable works for a positive range, it does not work for the negative.

Code: Select all

For i=Random(10, 5) To 0 Step 0
Debug i; will not happen
i-Random(2, 1)
Next

Is there a way around this?
It would be really nice if step could be a variable...

Code: Select all

 For i = 10 To 1 Step -1
  i +1 ;undo loop code
  i -1 ;anything
  Debug i
Next

Looks quite silly, but it works. Apparently the compiler only looks at the Step part, not that the For starts with a higher value and thus is decreasing in each loop.

Thanks, but that only works for negative.
If you were to do a -1 step with 1 to 10, that would still not execute, so it looks like I'll have to resort to a manual while loop.
The most recent case where I needed both was with the from, to, and step based on the variable, e.g.,:

Code: Select all

If ddirection=0
step_=1
from_=0
to_=10
Else
step_=direction
from_=current+direction
If direction=-1
to_=0
Else
to_=10
EndIf
EndIf
For i=from_ To to_ Step step_
; from 0 to 10 with step +1 if direction is 0, from current+1 to 10 with step 1 if direction is 1, and current-1 to 0 with step -1 if direction is -1.
