Fixed width fonts on the PC

[Jim Hurley]

I am porting a stack from the Mac to Windows. Unfortunately, I have 
little experience with Windows fonts.

In particular I need to know what fixed width fonts are common on the 
PC. I have found one, "Courier New" ("Courier," the old version, is 
very jagged in the size I need.)

What other fixed width fonts can I count on the user having  on his 
or her machine?

Thanks.

Jim
