--- Comment #2 from Simon Sobisch <simonsobisch at gnu dot org> --- Yes, U as per currently IBM (the COBOL Development group is in the process of adding it for the next standard). To handle the precedence - feel free to copy GnuCOBOL's implementation in cobc/tree.c, especially (valid_char_order) + (cb_build_picture), also handling U and GCOS' extension L.
