Hello,

I’m trying to create a function that return an array of 4, data type bool. I thought creating a record for this purpose is an overkill. Can anyone help me please? Thank you.

Hi,

a function can not return an array but you can use a procedure which returns the modified array.

Please refer also to the following thread “[Return an array of num from a function](http://forums.robotstudio.com/discussion/comment/23376/#Comment_23376http://)”

Example:

proc Example()  
var bool bArray{4};

!Call routine to set the data of the array  
ModifyArray bArray;  
endproc

!Array will be handled as by reference and returns the modfied values  
proc ModifyArray(INOUT bool array{\*}  
!use function DIM to get the size of the handed over array  
for i from 1 to DIM(array,1) do  
array{i}:=…  
endfor  
endproc

/BR
