I think this is a djgpp question rather than a comp.lang.c one.
Maybe not, but..  I have only one C compiler and its DJ's 2.0.

The stdio scanf() is giving me a fit.  First, if I only press
<Enter> when it is waiting for input, it hangs the system. Only
^C gets me out with a SIGINT to the DOS prompt.  Is that 'defined'
behavior?  This next one drove me crazy for an hour..

	double d = 6998.82;
	.....
	printf("Amount = ");
	scanf("%f", &d);

I type what I like, scan() executes but d doesn't change.  After
pulling some already sparse hair looking for bugs, I try compiling
it with -Wall and guess what.  gcc says "%f" is float and d is 
double.  I know that!  When I declare 'float d;', scanf() does as
expected.  Now I know that "%f" in a printf() string is promoted
to double.  Is this not the case for scanf()?  

I'm getting really tired of scanf().  

Joe
