Small subset of +[GNU assembler](https://sourceware.org/binutils/docs/as/) directives is recognized as well. +Next directives are recognized: `.word`, `.orig`, `.set`/`.equ`, `.ascii` and `.asciz`. +Some other directives are simply ignored: `.data`, `.text`, `.globl`, `.end` and `.ent`. +This allows to write code which can be compiled by both - integrated and full-featured +assembler.

If the +action is invoked and some of source editors selected in main windows +tabs then the "make" is started in the corresponding directory. Else +directory of last selected editor is chosen. If no editor is open then +directory of last loaded ELF executable are used as "make" start path. +If even that is not an option then default directory when the emulator +has been started is used.
