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			`; unsigned char __fastcall__ cbm_k_save(unsigned int start, unsigned int end);`
