Hi,
I need help with a project of mine.
I have a function witch look like this :

code

It basically contains 3 array for different data type,
and the last_pos array correspond to the last value added or remove in corresponding data arrays

Then i want a make multiple function witch can have impact on those array : example-
1- insert data
2- delete data
3- search for data

So i begin with a function that impact 1 of the array ( int) that can insert data in the array

The function code look like that :

code

So now.. i need help trying to make these function malleable for all the arrays in my struct : stdata_list
Basically being able to insert data in whatever list i need.
I'd wanna have something clean without have 3 set of copy paste code in my function.

Thanks everyone !

code section1:

TYPE stdata_list :
STRUCT
    ilast_pos   :   ARRAY[0..2] OF INT;//the position of the last record in the list
    idata           :   ARRAY[GVL.ZERO..GVL.MAX] OF INT;
    sdata           :   ARRAY[GVL.ZERO..GVL.MAX] OF STRING;
    stdata      :   ARRAY[GVL.ZERO..GVL.MAX] OF stitems;
END_STRUCT
END_TYPE

code section2:

FUNCTION finsert : int
VAR_IN_OUT
    stlist  :   stdata_list;
END_VAR
VAR_INPUT
    idata   :   INT;
END_VAR


IF stlist.ilast_pos +1 < GVL.MAX THEN   
    stlist.idata[stlist.ilast_pos +1] := idata;
    stlist.ilast_pos:=stlist.ilast_pos+1;
END_IF
