    Hi There!

    The following code seem clean and legal...

    FOR uiDiCh := 0 TO cuiMaxAmmount DO
   axDInValue[uiDiCh] := THIS^._abyIntRxBuf[7].uiDiCh;
END_FOR

    But the compiler states that bitaccess (_abyIntRxBuf[7].xyz) a literal or symbolic integer constant...
    Thus, I have to rewrite the code into;

       axDInValue[0] := THIS^._abyIntRxBuf[7].0;
   axDInValue[1] := THIS^._abyIntRxBuf[7].1;
   axDInValue[2] := THIS^._abyIntRxBuf[7].2;
   axDInValue[3] := THIS^._abyIntRxBuf[7].3;
   ..

    Has someone got any suggestions to solve this in a few lines of code instead of copying it the "dumb" way?

    Axdinvalue[0]:=(_abyintrxbufer[7] and shl(1,i))<>0)
