- LISP - how to create a bitmap file by script?
===

I'm a newbie here so please be soft with me =) 

I'm trying to develop a script in LISP  (sorry, no other language) to create a bitmap file.
I went on different web site about the bitmap format, but my concern is about the procedure itself.

Using LISP, (and perl / awk, my environment is Linux RHEL5) i can only create a text file with the 'regular' ASCII codes (i mean printable / displayable). 

My issue is about the chars that are not printable.
For example, if i want to put in the bitmap header the hexadecimal chain 00 00 00 00, what would be the corresponding ASCII code? 

how can i print them in a file? 

Thanks a lot for your help and clarifications! 

best, 

P-chan
