[Info-vax] Native compilers

[John Reagan]

With all the various threads talking about compilers and such, here's a "demo" (compilers are hard to demo) of a the native Macro compiler.

$ type hw.mar
.TITLE  hello
.PSECT RDATA,NOWRT,SHR,NOPIC,NOEXE,RD,QUAD
HI:     .ASCID /Hello, World!/
.PSECT CODE,NOWRT,SHR,PIC,EXE,RD,QUAD
START:: .CALL_ENTRY PRESERVE=<>,MAX_ARGS=0,HOME_ARGS=TRUE
PUSHAQ  HI
CALLS   #1,G^LIB$PUT_OUTPUT
BLBC    R0,10$
MOVL    #SS$_NORMAL,R0
10$:    RET
.END    START

$ show system /noproc
