The Filer is also fully customizable. Some variables can be stored in the HOME directory, and change the Meta Kernel behaviour. Some object types cannot be easily created by users, are lost when edited. Assembler The Masd assembler works directly on the HP48. It is fast, and new functions ease the writing of both little and big projects.
Links are a way to cut a big project in handable pieces.
A link, defined by ', includes a source file in the compilation process. One can create a high-level structure, global label being main functions entry points, local labels being only subroutines inside each function, and link labels are associated with a group of functions in a source file. Also, the less there are global labels, the less the compile takes. Instead of typing an address or a value each time it is necessary, define it once with a name, and then use with name in expressions. Also, if an address changes, you only have to change it once, and recompile the project.
