For full functionality as described here, the BrowseBox object requires the Windows Shell Library SHELL32.DLL Version 4.71 or higher. The BrowseBox object also supports the enhanced functionality provided by SHELL32.DLL Version 5 (Windows 2000) if present.

The BrowseFor property specifies the type of resource and may be 'Directory'(the default), 'File', 'Computer' or 'Printer'.

The StartIn property specifies the path name where browsing should start.

The HasEdit property specifies whether or not the dialog box contains an edit field into which the user can type the name of the folder or other resource, rather than browsing for it. The default is 0.

A BrowseBox may only be used by the execution of a modal ⎕DQ. The action code for the FileBoxOK and FileBoxCancel events must be set to 1 so that the appropriate result is returned by the modal ⎕DQ.

After the user has pressed OK or Cancel, the Target property contains the name of the chosen folder or other resource.

Example:

     ∇ DIR←{START_DIR}GetDir CAPTION;BB;MSG
[1]    ⍝ Ask user for a Directory name
[2]    ⍝ CAPTION specifies Caption for dialog box
[3]    ⍝ START_IN (optional) specifies starting directory
[4]    ⍝ DIR is empty if user cancels
[5]    :With 'BB'⎕WC'BrowseBox'
[6]        :If 2=⎕NC'START_DIR'
[7]            StartIn←START_DIR
[8]        :Else
[9]            StartIn←''
[10]       :EndIf
[11]       onFileBoxOK←onFileBoxCancel←1
[12]       Caption←CAPTION
[13]       HasEdit←1
[14]       MSG←⎕DQ''
[15]       :If 'FileBoxOK'≡2⊃MSG
[16]           DIR←Target ⍝ = 3⊃MSG
[17]       :Else
[18]           DIR←''
[19]       :EndIf
[20]   :EndWith
