MR 
DEBUG command 

Modifies contents of ST, X, DL, Q, S, Z, P, 1, 2, 3, and 4 registers.

SYNTAX 

          MR [ ,register] [ ,register] ,...

PARAMETERS 

register         The register to be modified.  Omitting this parameter
                 indicates all registers.  New values then are requested,
                 one at a time, in the form:

                      register = currentcontents := 

                 to which you respond with an expression to specify the
                 desired new contents, terminated by a carriage return.

                 If the input is invalid, :  = is repeated so you can
                 enter valid characters.  A carriage return alone (null
                 value input) preserves the current contents.

                 An ASCII period (".") terminates any further requests
                 for modification.  (Optional parameter.)


NOTE  The following restrictions apply to the MR command:

         1.  The register contents must be such that

             a.  DL< 0 < Q < S < Z

         2.  Only bits 2 through 7 of the ST register can be changed.


Privileged Mode 

All ST bits can be changed.
