MACRO-10 is an assembly language with extensive macro facilities for DEC's PDP-10-based Mainframe computer systems, the DECsystem-10 and the DECSYSTEM-20. MACRO-10 is implemented as a two-pass assembler. ==Programming examples== A simple "Hello, world!" program in MACRO-10 assembler, to run under TOPS-10, adapted from a specimen in a large collection of "Hello World" programs in various languages:〔Wolfram Rösler,("The Hello World Collection" ). Retrieved on 5 April 2009.〕 TITLE HELLO WORLD ; 'Hello world' in MACRO-10 for TOPS-10 SEARCH UUOSYM ; Make UUO symbol names available LAB: ASCIZ /Hello, world! / ; NUL-terminated ASCII string with CRLF START: RESET ; Initialise job to clean runtime state OUTPUT: OUTSTR LAB ; Output string starting at LAB: MONRT. ; Return to monitor JRST OUTPUT ; Restart at OUTPUT: if user CONTINUEs job END START ; End assembly, set program start address If this program is saved in the file HELLO.MAC, it can be assembled, linked and run like this (the TOPS-10 system prompt is the . at the start of lines): .COMPILE HELLO.MAC /DLIST MACRO: HELLO EXIT .LOAD HELLO LINK: Loading EXIT .SAVE HELLO saved .RUN Hello, world! .

A more complex MACRO-10 example program, which renders one version of the 99 Bottles of Beer song, may be examined at the "99 Bottles of Beer" web site.〔("99 Bottles of Beer" ) Retrieved on 10 April 2009.〕 For larger bodies of code, much of the MACRO-10 code for the TOPS-10 and TOPS-20 systems is available in the Trailing Edge PDP-10 tape archives.〔(Trailing Edge PDP-10 software archive )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「MACRO-10」の詳細全文を読む スポンサード リンク
