i am a little confused about what you are asking - lol
MASM is a Macro Assembler program, written by microsoft
i think they are up to version 11, now
MASM32 is a package of include files, libraries, utilities, examples, and help files
it was intended to be used with MASM, and even includes version 6.14 of the MASM assembler
however, it may be used with other MASM-compatible assemblers
that particular version of MASM is redistributable - most of us replace it with a newer version
as far as i know, Hutch is the original author
