Hello WKitty. foldhiddenmask : byte = 1 shl foldhiddenbit; currentfoldhiddenmask : byte = 1 shl currentfoldhiddenbit; foldlevelmask : byte = not (foldhiddenmask or currentfoldhiddenmask);
= msedatalist.pas(897,47) Error: (3203) Illegal expression msedatalist.pas(899,61) Error: (3203) Illegal expression msedatalist.pas(900,72) Error: (3203) Illegal expression Thanks for the links for calculation, indeed the result is -193. I did play with abs(), for example: foldlevelmask = abs(byte(not (foldhiddenmask or currentfoldhiddenmask))); But strangely still that warning: Warning: (4110) Range check error while evaluating constants (-193 must be between 0 and 255) Fre;D Fre;D ----- Many thanks ;-) -- Sent from: http://free-pascal-general.1045716.n5.nabble.com/ _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
