Automic UC4 script: Storing user-input into an array

Question

First: I'm using UC4 - dialog version 9.00A Build 234-162.

I'm trying to read a variable number of input fields (via :READ) and want to store their values into an array:

:DEFINE &FILE#, string, 10
:PUBLISH &FILE#[], , "WORKFLOW"

:BEGINREAD "Files"
:  READ &CNT#, , "Number of files", "3"
:ENDREAD

:SET &IDX# = 1
:BEGINREAD "Files"
:  WHILE &IDX# LE &CNT#
:    SET &IDX# = ADD(&IDX#, 1)
:    READ &FILE#[&IDX#], ,"???"
:  ENDWHILE
:ENDREAD

Problem is: Now I'm getting the error message U0020310 telling me the first parameter of :READ has to be a variable.

The Question: What am I missing? Is it impossible to use :READ with arrays? If thats the case: How can I work around that?

Answer 1

&CNT# has to be a Variable object (a VARA object). So you would read everything into a static VARA object.

This could than be looped through with a PREP_PROCESS command.
