I recently had an interest experience in using the three systems
above (MS-Pascal, TurboPascal, and MS-C). I wrote a filter program
that did some character level processing on a text file, before
outputting it (through the Tangent Technolgies PC Macbridge, usual
disclaimers...) to an Apple Laserwriter. The program basically performed
a state-machine processing and replaced certain macros with expansions
that were translated into things like headers for memos, etc., on the
LaserWriter. 

Having started with only MS-Pascal, I then recompiled using TurboPascal.
After acquiring a copy of MS-C, i rewrote the code in C. The intersting
part of all this is the resulting size and execution times, listed below:

  Data file size: 9744 bytes
  MS-Pascal executable:  25K bytes
  TurboPascal executable: 25K bytes
  MS-C executable: 10K bytes
  Time to execute:
	MS-Pascal           TurboPascal               MS-C
	---------           -----------              -------
	  2:55                4:37                    1:35
  (time in min:secs, includes access to network and printing)

This example is by no means a definite becnhmarking; and yet, for a first
time user of the various compilers on the IBM-PC, it seems that the various
claims of Turbo (fast faster fastest!!!) I have seen in some magazines are
somewhat overrated. The character level I/O seems to be most efficient in C,
and of the two Pascals, Turbo is definitely too slow.... It is nice to have
a fast compiler and integrated editor package, but if the code can't hack
it, I'll take the slow way during compiles every time!

(disclaimers galore: I don't work for any of these companies, and if I did
 they'd probably shoot me for sending mail like this...)

Without seeing the code, it is difficult to compare these.  What kind of
file did you use in the Turbo code.  Turbo Pascal is incredibly fast at I/O
depending on how you implement it.  It would be interesting to see the code
for these filters (at least the I/O parts)
