Embedding the Assembly Date and Time in a MASM 6.0 Object

• Microsoft Macro Assembler for MS-DOS, versions 6.0, 6.0a, and 6.0b
• Microsoft Macro Assembler for OS/2, versions 6.0, 6.0a, and 6.0b

SUMMARY

In the Microsoft Macro Assembler (MASM) version 6.0, predefined symbols for the date and time of assembly were introduced. They are:

   @Date
   @Time

MORE INFORMATION

The following sample code demonstrates two methods of embedding the information in a string in the object. Date1 and Time1 are constructed using one method, Date2 and Time2 using the other. Assemble with /Fl to get a listing that shows the expansion.

Sample Code

/* Assemble options needed: none
*/

tmp         equ <>
tmp         CatStr <">, @Date, <">
Date1       byte tmp

tmp         equ <>
tmp         CatStr <">, @Time, <">
Time1       byte tmp

%Date2      byte "&@Date"

%Time2      byte "&@Time"

start:

    mov ax, @data
    mov ds, ax

    mov ah, 4ch
    int 21h
