I'm writing a program which needs access to some large (8K-32K) chunks of data. These data are produced by other programs and wind up in data files. I'm currently just reading the data in from these files at run time, but would really like to able to link them into my main program. I could theoretically write a program (call it BIN2DB) which would take my binary file and make a huge masm file with a bunch of DB directives in it, but this seems like a real pain. What would be really perfect would be to have a utility (say BIN2OBJ) which would turn my file into a Microsoft OBJ with a public symbol at location 0. Then I could very easily access the data from inside my program. Has anyone tried anything like this? Or does someone have alternate suggestions?

Like, say, this program that I found by sending the message lookup /OBJ/ to rjc@math.princeton.edu, as per the instructions in the comp.sys.ibm.pc.misc Frequently Asked Questions file?

I used it in a previous life to stitch a p-SYSTEM binary into an MS-DOS loader program, but that is another story. In your executable, define a 32mb data area (global static data) initialized to a pattern you can easily find. Link so you get a map!!!. Rename .exe to .bin, read into debug. Using the offset from the map, look just before the 32 meg area for some lenght for the pattern. When you have found the address at which the block of data lives, just read in the file to that location from disk. Write the file back and change .bin to .exe. Hope you do not have to resort to this, but it worked for me in a past life. -- ----- Dion Hollenbeck (619) 455-5590 x2814 Megatek Corporation, 9645 Scranton Road, San Diego, CA 92121 uunet!megatek!hollen or hollen@megatek.uucp
