* Parse sign bit terminated string to convert it to a
* null terminated string. Note: if X and Y are the same
* the existing string will be overwritten -- don't do this
* with psects...

* OTHER MODULES NEEDED: none
 
* ENTRY: X=start of sign bit terminated string
*        Y=buffer for null terminated string

* EXIT: D=string size (not including null)
*       All other regs (except cc) preserved
