Step7 - how to initialise an array at run time?

[L D[AR2P#0.0]]

Can you amplify on "strange" ?

You cannot fill a boolean array with a bool - but that is specified in the help for SFC21.

When i tested, it i got partly filled array. Dont remember what i imput as "filler variable" might have been array of bools. If I remeber correctly help spoke only that when using bools, target must be disiviable by eight.

Although I'm only using ten bools, when I created the array as a STAT Step7 automatically allocated two Bytes, so that wasn't a problem.

it is difficult for me

That is always the case, as array boundary is word. So even if you have myArray[0..1] of bool, it takes space of word.

I made myArray[0..45] of bool, tried to fill it with bool, bool array and one member of bool array. None really worked. I could not even get it to work with myArray[0..7]...

Now I tried it again, using myArray[0..7] and byte as fill value and it worked. So dont know where my error was
