Using a good Assembler (like ASM-H with SLAC extensions) there is no need to
code such programmer-unfriendly code like
R0        EQU   0
HWORD     DS    H
          LH    R0,HWORD
          $IF   ZERO
          LTR   R0,R0
          $THEN

If your Assembler supports type- and length attributes in outer and inner
macros, if you add some own types like "Register" you can code the same
similar to "high level languages" like FORTRAN:
R0       #EQUR  0
HWORD    DS     H
         IF     HWORD,EQ,0,THEN

We started this type of programming in the late 60-th -- and stopped it
some years ago. If anybody is interested I will look for a description
and the corresponding macro-library.
