如何擴展TASM宏

Question

有沒有使用Borland的TASM擴展宏的方法？ 我想轉換一個TASM compatible .ASM文件來查看所有擴展的宏。 找不到任何選項來執行此操作。

使用TASM的命令行選項/ la生成擴展列表。從此列表中，您可以看到高級別和低級別的擴展。此功能在TASM的所有版本降至1988年

例如最初的版本，讓我們假設你有以下TASM宏：

OUTPUTMESSAGE MACRO hConsole,stringval 
LOCAL msg 
    .data 
msg db '&stringval',0 
    .code 
    call outputString ,hConsole,OFFSET msg 
ENDM ;OUTPUTMESSAGE 

你想看到下面的源是如何擴大：

OUTPUTMESSAGE hConsole,<This app was assembled with TASM version > 
OUTPUTMESSAGE hConsole,%??version 

與/ LA（I碰巧使用5.4版本）將產生以下所產生的列表文件：

516      OUTPUTMESSAGE hConsole,<This app was assembled with TASM version > 
1 517 0000018F     .data 
1 518 00000000 54 68 69 73 20 61 70+ ??0000 db 'This app was assembled with TASM version ',0 
    519  70 20 77 61 73 20 61+ 
    520  73 73 65 6D 62 6C 65+ 
    521  64 20 77 69 74 68 20+ 
    522  54 41 53 4D 20 76 65+ 
    523  72 73 69 6F 6E 20 00 
1 524 0000002A     .code 
2 525 0000018F C8 0000 00    ENTERD 00000h,0 
2 526      call outputString ,hConsole,OFFSET ??0000 
3 527 00000193 68 00000000r   PUSH OFFSET ??0000 
3 528 00000198 FF 75 08   PUSH hConsole 
3 529 0000019B E8 FFFFFE9B   CALL outputString 
    530      OUTPUTMESSAGE hConsole,%??version 
1 531 000001A0     .data 
1 532 0000002A 31 32 38 34 00  ??0001 db '1284',0 
1 533 0000002F     .code 
1 534      call outputString ,hConsole,OFFSET ??0001 
2 535 000001A0 68 0000002Ar   PUSH OFFSET ??0001 
2 536 000001A5 FF 75 08   PUSH hConsole 
2 537 000001A8 E8 FFFFFE8E   CALL outputString 

這些列對應於[深度] [行號] [偏移量] [機器代碼] [源]。不幸的是，你會發現，[line＃]列並不是特別有用。下面是從TASM5用戶指南剪斷描述列：

[depth] - indicates the level of nesting of Include files and macros within your 
      listing file. 

[line#] - is the number of the line in the listing file (not including header 
      and title lines). Line numbers are particularly useful when the 
      cross-reference feature of Turbo Assembler, which refers to lines by 
      line number, is used. Be aware that the line numbers in [line#] are 
      not the source module line numbers. For example, if a macro is 
      expanded or a file is included, the line-number field will continue to 
      advance, even though the current line in the source module stays the 
      same. To translate a line number (for example, one that the 
      cross-referencer produced) back to the source file, you must look up 
      the line number in the listing file, and then find that same line (by 
      eye, not by number) in the source file. 

[offset] - is the offset in the current segment of the start of the machine code 
      generated by the associated assembler source line. 

[machine_code] - is the actual sequence of hexadecimal byte and word values that 
       is assembled from the associated assembler source line. 

[source] - is simply the original assembler line, comments and all. Some 
      assembler lines, such as those that contain only comments, don't 
      generate any machine code; these lines have no [offset] or [machine_ 
      code] fields, but do have a line number.
