How does one make C: routines in one .fas file available to another .fas file? To further explain, I have a lisp file with standard routines I use that is loaded with all drawings. Other lisp files are loaded as needed for engineering design requirements. These later lisp files make use of the standard routines previoulsy loaded. When everything is in lisp format, it works. If I compile to .fas I get the following error message "Error: no function definition: function name." The fas files were created with the defaults under the project box. Do I need to change the project settings ort do I need to add some other command? I have found that in order to use DOSLIB, that I had to add (vl-arx-import "doslib2k.arx") to each file.
