Added comments to cbm.h. load/save returns oserror code. Added open/close and read (which is not tested yet). git-svn-id: svn://svn.cc65.org/cc65/trunk@637 b7a2c559-68d2-44c3-8de9-860c34a00d81 2001-03-20 21:06:04 +00:00			`;`

Use external symbols for the CBM kernal jump table functions. This allows to emulate these functions on platforms where one or more of these functions are not available (PET, CBM-II). git-svn-id: svn://svn.cc65.org/cc65/trunk@1544 b7a2c559-68d2-44c3-8de9-860c34a00d81 2002-11-19 23:02:47 +00:00			`.import CHKIN`

Fixed two more function that didn't clear the high byte of the function result. git-svn-id: svn://svn.cc65.org/cc65/trunk@4049 b7a2c559-68d2-44c3-8de9-860c34a00d81 2009-08-23 21:40:36 +00:00			`ldx #0 ; Clear high byte`
