Hi all!

	I'm trying to write a small program which probably has been written
a million times before... - A memory list showing TSRs, hooked vectors etc.

	I'm not interested in simply getting a program that can do it (I got
lots of them) but in how it's done.
                     ^^^

	I've located the first MCB and found its PSP. But there's no pointer
to th next MCB which I presume I need to get and follow repeatedly until I
reach the end of the chain. Is this correct?. Some of the information I need
is in the PSP associated with each MCB, other is in the MCB itself.

                          HOW IS THIS DONE ???

	If it has any relevance, I'm using PCDOS 3.30 and Turbo Pascal 6.0
for the experiments... The used format of a MCB and a PSP is taken from Ralf
Browns Interrupt List...


	LOTS and LOTS of thanks in advance!!!!!!

		Per.

PS: Source code for such a utility, in C, Pascal or commented assembler will
    also do.
