This is exactly what happens (and is supposed to happen using the static keyword on a global variable). > Any ideas on how to declare a unique global variable for all pages?? As with every C compiler, having a declaration extern BYTE language; in temete4.h (to be included wherever language is accessed) and a matching definition BYTE language = I18N_ES; in exactly one .c file (which is linked to the project but not #include'd) should grant access to a shared variable across your .c files. Of course, this will place language in exactly one of the memory banks of the PIC, requiring (automatically inserted) BANKSEL directives before access. There is no way to tell sdcc that a variable resides in a SHAREBANK so that accesses to it do not require BANKSELs. Even placing language in such a `bank' in some assembly source file would not help here. Hope this clarifies things a bit, Raphael ------------------------------------------------------------------------------ _______________________________________________ Sdcc-user mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/sdcc-user
