Setting Tool System Variable using Karel

My robot in Roboguide is CRX-10iA/L


I am using Karel to get and set tool frame value. This is my piece of code

    PosTool : XYZWPR

                    CASE(6): -- 'get_tool' request
                        WRITE('get_tool request',cr)
                        GET_VAR(entry, '*SYSTEM*', '$MNUTOOL[1,2]', PosTool, status)
                        IF status <> 0 THEN
                            POST_ERR(status, '', 0, 2)
                        ENDIF    

I am getting the error

INTP-342 ABORT (%s^4, %d^5) Incompatible variable

Cause: KAREL program error. The data type defined by the BYNAME function and the variable

type are mismatched.

Remedy: Make sure you have the correct data type and variable type.

I have tried every data type for PosTool but getting the same error.

I am out of ideas.

Any help is appreciated

hoitzing Do you see the updated value in the variable after it has been set?

Thank you, the it works with POSITION Data Type.
