How to pass <list_items> to a PULLDOWN DIALOG as a variable?

Question

In a PRACTICE script, how do I pass a list of items to a pulldown dialog as a variable. I have tried the following, but it doesn't seem to work.

&myFiles="foo,bar,baz"

DIALOG
(
    OptionA.SEL: PULLDOWN &myFiles ""
)

Answer 1

From the PRACTICE Script Language User’s Guide (practgice_user.pde):

Use (& or (&+ as opening block delimiter to switch ON macro expansion ...

The following works as expected:

&myFiles="foo,bar,baz"

DIALOG
(&+ ; <-- note this
    OptionA.SEL: PULLDOWN &myFiles ""
)
