Multi dimensionnal structure and word multidimensional VARARG 64 32

[TouEnMasm]

I have made the test with ML and the masm32 package.
It is as usual,the many limitations of ML don't allow to do what is perfectly correct.
Use UASM,JWASM or ASMC,I have not tested,but i am sure they work.
Five minutes later,I have tested UASM,JWASM,ASMC all three are happy with the code.
You have the choice.

Then, for sure, I maked something wrong

Hi TouEnMasm,

SETL (SET Language) is a very high-level programming language based on the mathematical theory of sets. It was originally developed by (Jack) Jacob T. Schwartz at the New York University (NYU) Courant Institute of Mathematical Sciences in the late 1960s.

Hello,
The vararg for 32 bits seem solved.
I try now to do the same thing for 64 bits.
I there is no more than four argument,no problem they are in rcx, rdx, r8, et r9.
A little help is needed for the five,six .. arguments,They are in stack ,How find the them ?

[TouEnMasm]

solved also The 64 bits form
I have tested it with uasm,jwasm and asmc64.
Little modifies  made.The X64 and X32 directories give the two samples.
Take care that uasm dont find the fifty element at the same place    (64 bits sample debut.asm)
