[Stackoverflow] [Progress OpenEdge ABL] SYSTEM-DIALOG GET-FILE with dynamic file type filters

[TheDrooper]

Using OpenEdge 11.7 and Windows 7, I'm searching for a disk file using this working code:

DEFINE VARIABLE cFileName AS CHARACTER NO-UNDO.
DEFINE VARIABLE lChose AS LOGICAL NO-UNDO.

SYSTEM-DIALOG GET-FILE cFileName
FILTERS "Text Files (*.txt)" "*.txt", "Comma-Separated Value Files (*.csv)" "*.csv"
UPDATE lChose.


Is there a way to dynamically build the filter list with a variable? I've tried this, which doesn't work:

DEFINE VARIABLE cFileName AS CHARACTER NO-UNDO.
DEFINE VARIABLE cFilters AS CHARACTER NO-UNDO.
DEFINE VARIABLE lChose AS LOGICAL NO-UNDO.

cFilters = '"Text Files (*.txt)" "*.txt", "Comma-Separated Value Files (*.csv)" "*.csv"'.

SYSTEM-DIALOG GET-FILE cFileName
FILTERS cFilters
UPDATE lChose.


I've also tried:

FILTERS VALUE(cFilters)


Both return an "unable to understand" error (198). Can this even be done?
