Using a library to call a preassembled .obj file

Jim Gilliam

I will try this again!! Surely there must be some one out there who can answer this question directly. I have written two files for a probject give below:

;Main Program (separate file)

extrn code (_test1)

cseg at 0

ljmp _start

main segment code
rseg main

_start:
lcall _test1
stop: sjmp stop
end

;program test1 (separate file)

public _test1

test1 segment code
rseg test1

_test1:
mov a,#99h
mov r0,a
ret
end

These two files are set up in a project and they work by calling test1 and moving 99h into the accumulator.

Now.....I would like to put test1.obj in a library file. For example, Mylibrary.

Now I would like to remove the _test1 file from my project and reference _test1 from my libray. What code do I use in the main program so that I can properly call the subroutine _test1?

Does any one out there understand my question and can directly answer it?

Thank you so much.

    Step 1: Actually create the library. See Chapter 10 of the "Macro Assembler and Utilities" manual for how, or just select option "create a library" on the "Output" tab of the target options of a new target that has test1.asm as its only source file.

    Step 2: Create a header file for it; let's call it "test.inc". The most important part of that header file will be a line like this:

    EXTRN CODE (_test1)

    which tells the compiler that "_test1" is defined somewhere.

    Step 3: Add the generated library from step 1 to the list of inputs for the "main" target, and add a line

    INCLUDE "test.inc"

    to main.asm to access the header file from step 2.

    If this doesn't work, you really should get from asking vague questions to providing some usable details, such as: *What* did you actually try, and *how* exactly did it fail?
