using simple variable as "start" value in FOR

[polyconnect]

Trying to passing a value to a FOR statement with a simple byte variable and it doens't work.
Am I doing it wrong ?
The first FOR doens't work, the second one works obviously.

;Variables
Dim start_value As byte

start_value = 10

For counter = start_value to 0
    Locate 1, counter
    print ("1")     
Next

For counter = 10 to 0
    Locate 0, counter
    print ("1")     
Next
end

Your counter is going down so you need to add step -1 to the end of the line.

indeed ! I (naively) assumed that GCB would deduce the direction from the value it gets.
thanks a lot

You don't need the minus sign but makes it more readable.

quick question : can we use a word as a counter variable ? I've tried but it seems it only counts to 255 and consider any higher value to be equal to 255

Declare a word, integer to long variable and then use this variable.

dim myWordCounter as word
for myWordCounter = 0 to 0xfff
        'do funcky stuff
next
