Error MSB3721 when trying to compile simple program

[revolution9540]

I am learning Assembly Language (x86) and I need to figure out how to make a register overflow using only variables rather than intermediate values.

I with to overflow the AX register by putting FFFF into a variable, moving that variable into AX, and then incrementing AX. However, I am running into problems. First off, I go to declare a WORD variable like this:

Code Select Expand

limitReg WORD 0

Then later on in .code I do this:

Code Select Expand

MOV limitReg, FFFFh
MOV ax, limitReg

However, I get the following error:

error MSB3721: The command "ml.exe /c /nologo /Zi     /Fo"Debug\pa2.obj" /Fl"PA2.lst" /I "C:\Irvine" /W3 /errorReport:prompt  /Ta..\..\..\..\..\..\..\Irvine\Examples\ch03\pa2.asm" exited with code 1.   C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V120\BuildCustomizations\masm.targets   50

I receive no other errors. Can someone please help me out?

Here is the entire code:

Code Select Expand

INCLUDE Irvine32.inc

.data; the data segment
limitReg WORD 0

.code         ; start code segment
main PROC ; start the main procedure

SUB ax, ax; zero out all registers to be used by subtracting their contents from themselves

MOV limitReg, FFFFh
MOV ax, limitReg


call DumpRegs ; dump the registers
exit

main ENDP ; end of main procedure
END main ; end of source code

Hi,

   If you use MASM, hexadecimal values need to start with a number.
so FFFFH should be 0FFFFH.

here is a template for Irvine32 code

notice the paths of the files - you may need to modify them

the floatio.inc, graphwin.inc, and macros.inc files are optional
you may not need them, but it won't hurt to add them if not used

the lib files are needed

the option casemap directive forces case-sensitivity in symbol names
you can leave it out, if desired, but i don't recommend it
