Can some kinf soul send it to me > please. XBRA is based on a old proposal by Moshe Braner (hence the name, 'eXtended BRAner'). It is a protocol for programs for revectoring system vectors and looks like this: dc.b 'XBRA' ; magic number for 'xbra was used' dc.b 'FOOB' ; 4 characters unique id for the program (should ; be printable characters, id's starting with '_' ; are reserved for Atari) oldvec: ds.l 1 ; contains old value of the changed vector newvec: ...here goes the new code... Using this protocol, programs can: - find out, if they are already installed - follow a vector chain up to the start This protocol is officially documented by Atari Germany and is used in ca. 100 german programs. ___________________________ cut here _____________________________________ Julian F.
