QUESTION

I'm modifying the XBANKING.A51 file and I need to know whether or not I must preserve the Accumulator in the internal library routines:

PUBLIC ?C?CLDXPTR, ?C?CSTXPTR, ?C?ILDXPTR, ?C?ISTXPTR
PUBLIC ?C?PLDXPTR, ?C?PSTXPTR, ?C?LLDXPTR, ?C?LSTXPTR

Do you know where I can find this kind of information?
