According to the documentation:
When used on a [ list ] short code, indicates the name of a program to be performed called to return a file containing the data to be displayed.
The documentation has a minor error in that it says performed whereas it should say called.
So when you have a program=xxxxx in a list shortcode, the program should return a file handle to a keyed file with the desired contents. Generally this would be a memory file, but id could be a *query* file or actual data file. Something like:
MakeCarList:
enter FileNo
open (hfn) "*memory*"
FileNo = lfo
write (lfo,key="0") "Ford"
write (lfo,key="1") "GM"
write (lfo,key="2") "Audi"
write (lfo,key="3") "Volvo"
exit
The Key value will determine the sort sequence. You will generally provide a IOLIST on the file then use the [ col ] short code to reference the desired columns.
Normally you would have a file on your system with the car models and simply open and pass back this file then define which column/field you want displayed.
Now if you do want to use a program and a text string you could use something like:
<p>[ttl]Cars[/ttl]</p>
<p>[form]</p>
<p>[execute perform"myprog;makecarlist"][list Cars$][data rowsep=/ text=(carList$)][/list]<br />
[list Cars2$][data rowsep=/]Ford/Gm/Audi/Volvo[/data][/list]
[/form]
</p>
Use the Execute to run your program to load carlist$ and the text= option in the [ data ] short code to pass the value. When you use the text= option, there is no [ /data ] needed.
