bruce l.: you are correct i left out the "="! i am trying to master basic! it's new for me!
please look at code below. i want to know how to write indicater that will screen (pass) and also draw
(plot)? can pass CALL a plot that draws two lines; avg20 and avg50?
is there an error in skeep first 49 below, how about avg50 w/ offset of 1?
'|*****************************************************************|
'|*** StockFinder RealCode Condition - Version 4.9
'|*** Copy and paste this header and code into StockFinder *********
'|*** Condition:Crossing MA
'|******************************************************************
If currentindex < 50 Then
Me.setindexinvalid '* skip first 49? price.avg(50,1) sum how many??
End If
'* else ?? do we need 51 bars to sum price.AVG(50,1)???
If price.AVG(20, 1) < price.AVG(50, 1) AndAlso price.AVG(20) >= price.avg(50) Then pass
'* 1) currentindex = sys count, left to right, old to current; 0k?
'* 2) isfirstbar = y/n, first (0) bar on left; ok?
'* 3) if summation or avg etc. start proc. at "currentindex" + 1; ok?
'* (ex) for avg=50; if curr < 50 then me.setindexinvalid (skip?); ok?
'**questions**
'* some indicators (macd) PLOT two lines; PASS has no lines!
'* 1) how do i call my PLOT code from my PASS code to draw line showing what i just
'* selected; avg20 crosing avg50?

Although I've read through your post several times, I do not understand the RealCode or questions being asked. Here are some statements that may or may not directly answer your questions but which should hopefully it least be related and head you in the right direction.
Conditions and Indicators are two different things with different functions. These functions cannot currently be mixed and matched in the same RealCode.
A Condition returns True, False or nothing (the nothing is returned using SetIndexInvalid).
An Indicator returns a Single Value, a Bar or nothing (the nothing is returned using Plot = Single.NaN). The only way it can return more than one Value is by returning Bar data. When returning Bar data, you must return exactly four Values per Bar.
To Plot two Lines, you would need to use two Indicators.
Price.AVG(50, 1) will not have enough data to calculate until CurrentIndex = 50 (the index is zero based).
