Post subject:  How many are using mumps (MV1)?

I am interested in determining how many people are using MV1 for work or for play and on what platforms. Besides that, I couldn't resist being the first 2012 post.

Would appreciate replies from MV1 users...

Hi all and a Happy new year!
I use this implementation for some of my small apps. Unfortunately I was not successful with porting bigger apps from DSM/MSM (clinical IS, VA Fileman) - for some language incompatibilities - mostly in a routine reference combined with indirection. Also, it would be nice to have the possibility to access more than one database volume (seems that most of the modules are ready to handle it).

Hi, When I originally wrote MV1, I converted my major app from a DSM/MSM environment. The main difference probably was I seldom used routine indirection; I had the same problem trying to eradicate some bugs for Terry Wiechmann (never did get it correct).

Yes, most of the code is there for additional data volumes - I just never needed it as the max size of one volume is quite huge (approx. 512 terabytes).

For play... Nothing serious yet. Just finished the post on writing how to compile it on Xcode 4.

For now, I am developing/running it on Mac OS X 10.6/10.7.

I have two main interests:
1. I am learning C, and the code is exceedingly well documented. It's a good learning ground. My accolades to all the programmers.
2. I am interested in running VISTA on MV1.

I have been investigating why it doesn't run on 64 bit platforms, and I figured that the block start offset is hardcoded, when the structure size for the block differs on different platforms.

I am using 32 bit because x86_64 maps a 4G page zero to catch pointer truncations with a SIGSEGV. I need the base of SYSTAB to be below 4G for compatibility with linux and FreeBSD - I'll do a workaround someday.
