func cmbpindex

Syntax

   cmbpindex (cmaddr [pin])

This function accepts the address (either logical or absolute) of an existing CM breakpoint and returns the logical index number associated with that breakpoint. The default action is to look for breakpoints set by the current PIN. Breakpoint indices for other PINs (including the global PIN) may be retrieved by utilizing the optional pin parameter.

Formal Declaration

cmbpindex:u16 (cmaddr:cptr [pin:s16=0])

Examples

   %cmdebug > bl

   CM      [1] PROG % 2.3401    TEST'SCREEN+%26

   CM      [2] PROG % 0.347     TEST'FILES+%0

   CM     @[1] SYS  % 161.5274  FOPEN+%0

First, list the existing breakpoints.

%cmdebug > wl cmbpindex(TEST'FILES)

%2

Go find the CM breakpoint index associated with the address TEST'FILES.

   %cmdebug > wl cmbpindex(FOPEN)

   No breakpoint exists in the breakpoint tables with that address.  (error

   #1080)



   Error evaluating a predefined function.  (error #4240)

     function is"cmbpindex"

       wl cmbpindex(FOPEN)

Now, go find the breakpoint index for the breakpoint at FOPEN. In this example we get an error. This is because we did not specify a PIN and thus searched only for process local breakpoints. We do not have a process local breakpoint at FOPEN.

   %cmdebug > wl cmbpindex(FOPEN, -1)

   %1

Go find the breakpoint index for the breakpoint at FOPEN. This time we specify a -1 to tell the function to search the list of system breakpoints.
