I just have started to learn assembly. I made program below but compiler showed two error messages to me. First one is in the line number 30. The content of the message is: Operand types do not match. The content of the second message is: Unexpected end of file encountered. Its in the line nr. 34. I am using TASM compiler. The program main task is find the smallest number of the array.

What I have tried:

I tried to replavce

mov     ax, Najmniejsza

with

movzx ax, byte ptr Najmniejsza

but its still does not work.

The syntax used by x86 assemblers differs slightly. So you have to read the corresponding manual.

To load an address into a register, TASM uses the OFFSET keyword:

Borland Turbo Assembler User's Guide:
If you wish to refer to the offset of a symbol within a segment, you must explicitly use the OFFSET operator

mov     ax, OFFSET Najmniejsza

The error "Unexpected end of file encountered" is probably sourced by the wrong END statement. It must be like

END Start

I recommend to get a copy of the Borland Turbo Assembler User's Guide. It can be found in the web as PDF file.
