Shorter schedules!
"I had a deadline to convert a UNIX program to DOS.
Ten days remained, and I could see I would not finish using compilers
and conventional debuggers. I bought InstantC and converted and
debugged my program. Even with the extra time to become proficient
in InstantC, I did finish the project on time. Since then I've saved
two more critical projects against 'impossible' deadlines. My
company thinks I'm a wizard."

Compile and links in less than a second means that you program by making small coding changes and immediately executing to examine the effects and test all the results -- so that you can keep your concentration on solving the problem at hand.
With InstantC's incremental compilation technology, you can start testing most edits to your program in less than a second.
Since you can usually replace functions while your program is still executing, you can continue testing without having to restart your run, saving even more time.
