func cmva 

Returns the virtual address of a specified CM code address.

Syntax 

      cmva (cmaddr [pin])

Compatibility mode code may be emulated or translated into NM. This
function always returns addresses based on emulated CM object code.

Another function (CMTONMNODE) can be used to locate the nearest
corresponding NM node point address if the CM object code has been
translated into NM.

Refer to appendix C for a discussion of CM object code translation, node
points, and breakpoints in translated CM code.  See the T(ranslate)
commands in Chapter 4 for additional information.

Formal Declaration 

      cmva:lptr (cmaddr:cptr [pin:u16 = 0])

Parameters 

 cmaddr          A CM code address to be converted to a virtual address.
                 Both logical and absolute code addresses are supported.

 pin             The process identification number (PIN) to which the
                 code segment belongs.  If pin is not specified, it
                 defaults to 0, which is defined to be the current PIN.

Examples 

     $nmdebug > wl cmva(cmpc) 
     $26.0000124c

Convert the current CM logical address pointer, for the current PIN, to a
NM virtual address and display the result.

     $nmdebug > wl cmva(SYS(%23.%250,$24)) 
     $3f.00000250

Convert CM logical address SYS %23.%250, for the process associated with
PIN $24, to a NM virtual address and display the result.

     $nmdebug > wl cmva(CST(3.0)) 
     $21.000034c4

Convert absolute CM address CST 3.0, for the current PIN, to a NM virtual
address and display the result.
