array syntax, loading modules and searching.

Robot Controller

Hi Everyone, I’m having a problem with syntax for searching for an array.

  1. I want to load a module in an order defined by an array:
    CONST string Modules{4}:=[“mod1.MOD”,“mod2.mod”,“mod3.mod”,“mod4.mod”];
    PROC Load_module()
    FOR i FROM 1 TO Dim(Modules,1) DO
    Load\Dynamic,diskhome\file:=“Modules{i}”;

Within this module are a listing of RobTargets, and another array (called “Positions#” where # will change for each module) defining the position that I need the robot to work. These are large – 2000 points and the array with 2000 names in it.

  1. Once that module is in memory, I want to search it to look for the array that contains the robtarget order:
    SetDataSearch “robtarget”\Object:=“positions."\INMOD:=“mod{i}.mod”\GlobalSym;
    getDataVal "positions.    ”,targets;

This is the problem area – I want to assign “positions#” to another array name “targets” so that my main program can maintain a generic variable name.
Would someone be able to help with the syntax?

thanks Darren

Hi,

as described in the section “Limitations” in the chapter “SetDatasearch” in the reference Manual it is not possible to search for Arrays.

In this case you can only use the instruction GetDataVal and verify if the error ERR_SYM_ACCESS is not raised, to know if array is available.

To be able to read the Array you have to define another array defined with the same size as variable (VAR) and use this as Parameter for GetDataval instruction.

e.g.

FUNC bool ReadArray(num Index)

VAR robtarget pArray{2000};

GetDataVal “Positions”+ValtoToStr(Index),pArray;

RETURN true;

ERROR

!Array not available

IF ERRNO= ERR_SYM_ACCESS RETURN FALSE;

ENDPROC
