Tomasz,
Okay, using static variables is the method required. I attempted to
use these in the best manner in which I could interpret the brief
description in the documentation. My attempts failed. I re-read and
re-read the info in the URL's you presented here, and even studied
the 'text string' versions as well. Although I am a skilled
programmer in VB and other languages, unfortunately the description
of usage is NOT sufficient for me to properly apply these functions
in my AB Exploration. Would you kindly give an example coding that
shows SPECIFICALLY how a VARIABLE AND the 'StaticVarSet'/'...Get'
functions are to be used with each other. For instance, I tried the
following code snippet without success -- I get a COMPILER error
telling me (paraphrased) that '...variable 'm' needs to be first
initialized':
---------------
a=StaticVarSet("m",0); //initialize variable m
....
IF (Filter[barcount-1]) //test a Filter condition (THIS works)
{
...
m=m+1; // increment variable m
...
}
AddColumn(m,"Count",4.0); // display CURRENT value of m in a column
----------------
I then tried using: a=StaticVarSet(m,0); [WITHOUT the " (quote
marks) around the variable m, but still no success].
I've read the documentation over and over again, and tried MANY other
alterations, but without success over the past two days. Apparently,
I am missing something very simple, but it's not obvious to me. A
better example than the 'StaticVarGetText' one, specifically using a
NUMERIC variable would be highly appreciated.
Thank you again for your assistance.
Buzz
