       /IDENTIFIER_CHARACTERS=string

    Specifies the characters that may appear in token and alias names
    in that language. This list of characters is used in various
    contexts for the /INDICATED qualifier.

    The list of identifier characters also determines what LSE
    considers to be a word. A word is a sequence of identifier
    characters, possibly followed by one or more blanks. All nonblank,
    nonidentifier characters are considered to be distinct words.

    If you do not specify the /IDENTIFIER_CHARACTERS qualifier, LSE
    supplies the following values by default:

      "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ%$_0123456789"
