Hi, In an attempt to free some code space, I'm looking at a couple of options; a) preventing the compiler from automatically placing all string constants in the common code area (regardless of in which banks the strings are used) or b) locating all string constants in XDATA. I gather I'll need to use OMF2 and STRING and maybe XCROM directives (and LX51). I'm missing something obvious with this option though, since the initialisation strings for these constants will have to be somewhere within the code, so where does the saving occur? Has anyone experience or recommedations with either of these approaches? Thanks, David
It's not at all 'needless' that the constants are in the common area, and thus visible regardless of the current bank. The compiler cannot know which routines in which banks may, at some time or another, have a pointer to your string as one of their local variables. Given that, the string has to be available to all banks --- i.e., it has to be in the common area, if it's in code space at all.
