I ported my Hexdump again,
 this time to DOS 16-bit version! Assembly source file is included (using DOS int 21h interrupt).But it supports small file below 64KB, as I still don't know how to convert 32-bit number to hexadecimal in DOS.  I upload to here as my backup, since I don't use GitHub for these kind of projects. Attached File(s) 
HEXDUMPD.zip ( 1.91k )
