Hello

I've done a program which i've resized memory block using an ending segment to calcule program size and i've reserved memory for a temporal buffer. For the first step I've seen that is not sufficient defining variables with reserved memory, i need fulfill them whith zeroes (for example) to can calculate the size of the executable. For the second issue I've checked that is not a good idea to use "STACK 100h" for example, instead:
SEGMENT Stack
TIMES 100h DB 0
[...]
SEGMENT Text
MOV SS, Stack
MOV SP, 100h-2

With this changes, the program works fine. The final executable is shorter than the same in MASM and NASM compilers.

My question is: Is there a way to do this program in another finer way?
Is it possible to reserve memory in variables?

Thank you

You can set the stack up also this way:
