I'm using the Metalink compiler, and the calling command I'm using is CALL. As told in the manual, the compiler can automatically detect whether it is LCALL or ACALL.....
1) to my best knowledge, Meatlink never made a compiler. The metalink assembler, however is more or less the industry standard.
2) LCALL is an assembler instruction, I know of no compiler recognizing it, Forth?.
