I have used Fractint V17.2 with great interest.  I would like to contribute,
perhaps by adding another modules eg. animation for IFS. But I am facing the
problem of compling the source listings now:

with reference to Fractsrc.doc, it is required that those who doesn't have
Microsoft 6.00A should compile the parser.c, loadfile.c, calcfrac.c with no
optimation and use the /qc option. Therefore I tried to edit makefrac.bat and
Fractint.mak, including the following commands for the three specific files:
	cl /AM /W1 /FPi /c /DC6 /Gs /qc

After the compilation, Fractint.exe was created. But everything seems OK except
for the fractal type L system, which displayed nothing whenever I selected any
.l files. 

I wonder what is going wrong. I would appreciate if anyone could help.
