I'm a rookie on and this is mine fist question:
how can I compile an .API macro using SCASM?
Can some one help me posting an example?

Tnx in advance

You dont actually compile the macro as a scasm file. what you do is create a source file ( *.sca ) and compile that with scasm. within the source file you would call the API Macro in the compilation process to generate a BGL file to show the object. Anotherway is to use programs like FSSC to include your API in the design stage and then FSSC would compile all the code into a working BGL file wich would allso include the API Macro code that you input via FSSC or Airport for Windows !
