Once you have divined how the tools are invoked (through shell scripts, cunningly named .EXE files, etc - did you notice that all the EXE files are the same ??? ) iserver -sr-ss-se-sc tool.btl <tool parameters> -xm the XM option allows it to be reinvoked as follows :- iserver -ss-se <tool parameters> -xm and again .. iserver strips the command line of all switches it thinks are for itself and passes a doctored version to the tool of everything else. the -sz switch on iserver is a handy (hidden) switch for debugging. > 2. The linker is horribly slow ! Yes, it is. -xm doesnt help you much I'm afraid - most of the time is spent reading in the libraries. > 3.

It is about 502 bytes, which is the iserver max packet size less some control bytes. You can call again with the pointer moved appropriately. fread and fwrite do this for you.
