Subject: sequencer programs in an IOC

Hello everyone,
I'm trying to understand an IOC that generates a controls monitoring webpage at STAR.  For whatever reason, the IOC is not writing the html file that it should be (it has worked in the past).

The source code is a number of .stt files, each of which handles variables for a different subsystem.  Ultimately all of these variables are brought together using a file called overall.stt, and the webpage is written by a file called overallhtml.stt. 

When the IOC is compiled, these .stt files produce .c files of the same name.  What I'm wondering is, how are these c files used?  Do they become binary files when the IOC is compiled?  What generally happens in an IOC between these c files and a sequencer program being called in the start up script for the IOC? 

The sequencer programs are loaded as follows in the IOC startup file:
seq mot_gas
seq trig
seq eemc
seq bemc
seq tofm
seq overall
seq overallhtml

Are these binary executable files that are being called, or does the startup script read the c code directly?  I can't find any binary files by these names on the computer, but I see no errors while compiling either.  If anyone has any insight I could use a hand.  I know you won't know specifics on my setup, but any help with sequencer programs in general would be nice.

Thanks very much!
James Ross
