You should read the relevant portions of the docs first.  A few chapters 
of the GCC on-line docs explain the inline assembly facilities of GCC.  
Their syntax is significantly different from that of other DOS compilers, 
so you are in for some pretty nasty guesswork if you don't read those 
docs first.

The syntax of the assembly instructions is also different.  The DJGPP FAQ 
list (available as faq102.zip from the same place you get DJGPP) explains 
these differences in short in Chapter 17, and also points you to the full 
docs on this issue.

For examples, download the library sources (djlsr112.zip) and look in 
there.
