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. Jim Gilliam

This is one of the key differences between C / Assembly on one hand, and more "module-centered" ones like Pascal, Modula or Java. In C/Asm, using code from some other module or library always requires two steps: *) Adding the actual module to the list of things to be linked. *) Adding the interface declaration to the source files using it. A usable library thus always consists of at least two files that belong together: the object files (or library collecting them), and the header.
