MASM 6.0 can be had from most mail order firms for around $100 - $125.  All
versions of an assembler can work with QB - but with
differing levels of complexity.  Some don't support MS
Basic directly.  The main result of that is you must use
direct stack techniques to retrieve your stuff from the
parameter list rather than using a variable, and you must
POP them back off the stack before returning to QB.  MASM
has the .MODEL ...,{language} support, which PUSHes DS and
POPs DS and your parameters upon return.  No big deal if
that's not supported, but a little more cryptic:

.MODEL MEDIUM
.PUBLIC
.CODE

IsNull PROC
     PUSH DS
     PUSH BP
     MOV  BP,SP
     MOV  [BP+4],BX     ; This would get the LAST parameter - that is,
                        ; the string descriptor address in the case of
                        ; IsNull, much more cryptic than:

IsNull PROC Strg:Word
     MOV  BX,Strg
