is it possible to automate entry/change of data2?

["Romi Ghose" <r.ghose@xxxxxxxxx>]

Is it possible to write an EL (an indicator) that can change data2 to a
certain symbol when I enter/change data1 to a another certain symbol?  Eg:
Lets say I have AMZN as data1 and YHOO as data2.  Can I write an indicator
in EL (say "AutomatedChart") and insert it on my existing chart...the
indicator containing something to the effect that if data1 is changed to LU
then data2 will change to NT automatically.  The goal is to avoid the manual
task of looking up that NT is a related stock of LU (from my list of related
stocks), then deleting data2 and then going thru the process of inserting a
new symbol as data2.  Wonder if getsymbolname can be of any help here.
Or is it totally outside the scope of the software?? Using PS2Ki SP5.

Thanks in advance for any help in this direction.
