I want to be able to access host formats actually, for use in a listbox 
component

Chip,

I’ve been using Pluggers API pack plugin and this method, which works fine for 
formats. It may be that OBJECT Get filter and OBJECT Get format would do what 
you want (from v15R5, according to the dox).

Jeremy



  // resolve a format name into its string

  // $1: name

C_TEXT($0;$1;$resolveName)
$resolveName:=$1
If (Substring($resolveName;1;1)="|")
$resolveName:=Substring($resolveName;2)
End if 

C_LONGINT($i;$err)
C_TEXT($root;$filterRoot;$name;$value)
C_BLOB($res)

  //%w-533.4 no "missing parameter to plugin" message from next line
$err:=API Get Indexed Resource ("ST4D";1;$res)

If ($err=0)
$res:=API Bag To XML ($res)
$root:=DOM Parse XML variable($res)
If (OK=1)
ARRAY TEXT($names;0)
$filterRoot:=DOM Find XML element($root;"bag/filters";$names)

For ($i;1;Size of array($names))
DOM GET XML ATTRIBUTE BY NAME($names{$i};"name";$name)
If ($name=$resolveName)
DOM GET XML ATTRIBUTE BY 
NAME($names{$i};"value";$value)
$i:=MAXINT
End if 
End for 

DOM CLOSE XML($root)
End if 

$0:=$value
End if

Chip… I don’t think directly… but, you can via a “Host” method that you call 
from the component and return the value from that method to the component.
