Introduction
============
This repository provides minimal fixes to FOIA VISTA code, in order to allow
for a functioning VistA instance. These fixes are needed for both Cache and
GT.M. This repository covers only non-Kernel routines; see the Kernel-GTM
project (https://github.com/shabiel/Kernel-GTM) for Kernel infrastructure
enhancements.

Fixes are under Apache 2.0 where applicable.

List of fixes/Change Log
------------------------
* ICDEXA2 (passim): Don't convert codes to numbers. Codes may exceed implementation defined limit for numbers. On YDB, original code goes into infinite loop.
* (removed in revision 5) GET1+3^ORWORR1: Replace && with commas for if, to enforce 'and' with no side effects.
* (removed in revision 4) EN+16^DGRPD: Errant space needs to be removed.
* PATIENT^MPIFXMLP: Change to ZPATIENT so that it won't be found by patient registration. We can't use MPI outside of VA.
* DIUTL: Upstream fix from MSC Fileman 1060: $ZREFERENCE is not standard.
* HLCSTCP3: USE command arguments are vendor specific. Check for M Virtual machine implementer before choosing USE command arguments.
* ICDEX: MD tag missing quit, resulting on ,M11, error on GTM/YDB.

Install Instructions
--------------------
These routines are not intended for installation as a KIDS build. It's up to the end users on how they wish to apply them.
