View source for FLAVA

A utility that attempts to figure out the flavour of the current Pick environment.  Designed for use when writing portable code.

TODO: 1) test!, 2) add probes for more flavors, 3) some environments have different emulation modes - maybe return that as a "sub-flavor"?

Contributions welcome!  Please free to edit this page, or submit pull-requests at https://github.com/ianmcgowan/SCI.BP/blob/master/FLAVA

* Probe for jBase, thanks to Andrew Cole <andrewcole50@gmail.com>
* SYSTEM(1021)<4>. When I run that on my system
* "Copyright (c) 2018 jBASE International. All rights reserved".
*
X=SYSTEM(1021)<4>
IF INDEX(X,'jBASE',1) THEN CRT 'jBASE' ; STOP
*
* Probe for Unidata/Universe
* From: http://www.rsusers.com/cms/pages/wiki.wsp?page=112 (What's the min ver for this?)
*
X=SYSTEM(9010)
IF INDEX(X,'UD',1) THEN CRT 'UD' ; STOP
IF INDEX(X,'UV',1) THEN CRT 'UV' ; STOP
*
* Probe for D3/Cache
* https://www3.rocketsoftware.com/rocketd3/support/documentation/d3nt/103/refman/index.htm
* crt system(100)
* D3UNIX:RS6000;AIX;pick0:prod0;2;3;000047311000;6.0.0.m0;27 May 2001
*
X=SYSTEM(100)
IF INDEX(X,'D3',1) THEN CRT 'D3' ; STOP
IF INDEX(X,'CACHE',1) THEN CRT 'CACHE' ; STOP
*
* Probe for OpenQM - this is pretty weak sauce, do this last
*
X=SYSTEM(1012)
IF X # '' AND X # 0 THEN CRT 'QM' ; STOP
*
* No matches, let's display all possible values
*
CRT 'No match, does anything in this list look good?'
FOR F=1 TO 10000
  IF SYSTEM(F) # "" AND SYSTEM(F) # 0 THEN CRT F, SYSTEM(F)
NEXT F
