A DECUS member in Sydney Australia has requested some help with a 
problem as follows.

They are using WHITESMITH's "C" on a PDP 11/73 based system 
running RSX.

The "C" tasks end up being very large (around 400K bytes for a 
normal program that is around 100K bytes on a PC).

The programs seem to run very slowly - appear to be CPU bound and 
dont seem to run as fast as on the PC.

Questions are as follows:- 
1. Are there known problems with Whitesmith's "C" under RSX.

2. How does it compare with the DECUS "C" (in library as 11-SP-18)

3. Are there other versions of "C" that will run under RSX.

4. Is there something silly about the installation/configuation
  that would account for the poor performance.

Replies please to     GEREMIN@decus.com.au
Thanks in Advance.
