Registers


Registers at entry use standard linkage conventions with these exceptions:

  • R0 - Address of ALPDSECT. This address is the Audit List parameter block. The DSECT is obtained from macro$DLAMAP ALP=0.
  • R1 - The address of the log record or zero which is the end-of-file indication. The log record is mapped by DSECTs LGRDSECT, DLSREC, and several others depending on the type.
  • R13 - Address of a save area in a pre-chained save area set. You may use one or more of the save areas, but you cannot alter the chain.

 

Tip: For faster searching, add an asterisk to the end of your partial query. Example: cert*
