Nokia lcd include , small footprint to suit pic16's

[richard]

turns out that testing the bit vars "inverted" and "bigtext" was not always working after the asm section in gcga subroutine .this only shows up when some vars are pushed out of bank 0 .I can not establish the failure mechanism ,seems i'm just guessing what "CHK?RP" AND "RST?RP" macros actually do . I can't find their definitions anywhere . making the vars into bytes and manually setting correct bank fix the issue.
here is a more complex demo and an amended nokia include file to test and overcome this issue
