%1 = Channel number %2 = Block number, label

On accessing an individual frame element, a frame component other than TRANS, ROT, SCALE or MIRROR was addressed or the function CSCALE has been given a negative scale factor. Example: $P_UIFR[5] = CSCALE (X, -2.123) The frame components are either selected by means of the keywords TR for translation (TRANS, internal 0) RT for rotation (ROT, internal 1) SC for scaling and (SCALE, internal 3) MI for mirroring (MIRROR, internal 4) or they are specified directly as an integral value 0, 1, 3, 4. Example: Access to the rotation around the X axis of the current settable frame. R10=$P_UIFR[$AC_IFRNUM, X, RT] can also be programmed as: R10=$P_UIFR[$AC_IFRNUM, X, 1]
