[MEDITECH-L] CS 5.54, Getting Min/Max Values in a Macro... Possible?

[Joyner, Jim]

Hello all..
I'm looping through a set of data in a Macro in NPR, trying to find the
HI and LOW values..

First, if there is a 'function' or something that already exists, I'm
not aware of one. If there is, what is it?? Assuming there isn't.. I've
written the following macro, but it ins't working! Argh!

Here is my macro (simplified version)...
==========
; initializing my variables
0^/ZZZ, (that is a zero!)
""^/BPMH^/BPML^/BPMT,
;BPMT IS MY temp value, bpmh is my HI, bpml is my LOW
@GET.DATA,
; some more stuff

GET.DATA
;loop through and look get values
DO Loop{
@somefield.value^/BPMT,
@SORT.DATA,
NEXT Loop}

SORT.DATA
IF{/ZZZ=0 /BPMT^/BPMH^/BPML;IF{/BPMT'</BPMH /BPMT^/BPMH;/BPMT^/BPML}},
/ZZZ+1^/ZZZ
; essentially how this works is the first time through (zzz=0) set the
high and low equal to the temp value
; then the next times.. If the temp is GTE high then set high = temp,
otherwise set low=temp.
=========

On my picture, I am getting the correct HIGH value to show up.. That
works!
But.. My LOW is always BLANK or empty.. Never populated..
What am I doing wrong!?

TIA!

Its been awhile since I have actually done any REAL coding but here is
some pseudo code I would use to gather the minimum / maximum - assuming
they are integers or real numbers.

Using the ! operator as maximum and the & operator as minimum.

Pseudo code:

;
; Start Loop
;
INITIALVALUE^MIN^MAX,
;
DO{1 NEWVALUE!MAX^MAX,
NEWVALUE&MIN^MIN},
;
; End Loop
;
N("Maximum=",MAX)^#,
N("Miniumum=",MIN)^#,
;
;
END

Hi Jim

Try This

""^HIGH^LOW^NDX,
DO{+VALUE[NDX]^NDX IF{'LOW VALUE[NDX]^LOW;
LOW>VALUE[NDX] VALUE[NDX]^LOW},
IF{'HIGH VALUE[NDX]^HIGH;
HIGH<VALUE[NDX] VALUE[NDX]^HIGH}}

Replace VALUE with your structure

This should work

Hope this Helps
Ken
