I'm using 2 ways of defining content of popup menus.

First is to read list of values from INI file, then build popup, user picks 
some value, then I read from INI, vhat to do after choosing that value
INI looks like
[Actions]
Customers form=List all customers,Do something,Do another thing,*CRM
*CRM=Task 1, Task 2

[Actions call]
List all customers=library,:CRM:act,LIST,:CRM:list.rsl
Do something=library,:CRM:act,SOME METHOD,
Do another thing=library,:CRM:act,ANOTHER METHOD,
Task 1=library,:CRM:crm,TASK 1,:CRM:task1.rsl
Task 2=library,:CRM:crm,TASK 2,:CRM:task2.rsl
;name={library,script,form},name of library-script-form,vhich method to call 
in that library,which report to print at the end

And if I am standing on form "Customers", and uses clicks Actions button,
I read from INI list of actions for this form (*CRM means SubMenu), her user 
selection,
ant then call library or script or another form.



Second way of using PopUp in on some fields as "lookup" function.
But only for fields I know, have not more than 100 different options.
User enter something in filed and presses CTRL+space.
I read, what user entered in field, run a query ..value.. on lookup table, 
put list of options in popup and display.
