How can I initialize a Boolean value?

I'm trying to initialize a Boolean value in a managed COBOL project, but I cannot find in the documentation on how to do this.

The last line in the following code excerpt results in an "COBCH0229 Incompatible qualifiers" error:

CLASS-ID X.Form1 IS PARTIAL INHERITS TYPE System.Windows.Forms.Form.
  WORKING-STORAGE SECTION.
    01 isItTrue PIC 1 USAGE IS CONDITION-VALUE VALUE TRUE.

 

How can I initialize a Boolean value in the WORKING-STORAGE SECTION?
