assembly

Hi, once again I'm doing MASM programming. I'm trying to write a procedure using the Irvine32 library where the user enters a string which is put into an array of BYTEs with ReadString. Then it loops over that arrray and determines if each character is a number. However, when I try

cmp [buffer + ecx], 30h

MASM complains about comparing two things that are not the same size. Is there anyway I could read the ASCII code in each BYTE in the array as a DWORD (or otherwise extract the ASCII value in each BYTE)?

The problem is on the mov si, offset msg that in the first case transletes… >>> More
