    At the NCAR Graphics level of the utility PLOTCHAR, the error message Cathy
    Smith reports is the result of using a string in which the "function code
    signal character" is used improperly. For example, if I use the character
    string

       'A:S:2:N:/B:S:2:N:'

    in a call to PLCHHQ, it will write the equivalent of

       "A squared divided by B squared"

    The colons are being used as "function code signal characters"; in between
    pairs of them, PLCHHQ expects to see "function codes". If I misplace one of
    the colons, as in

       'A:S:2:N/:B:S:2:N:'

    then I will get the error message reported. Also keep in mind that, although
    the colon is the default "function code signal character", another character
    can be substituted. For example, I could do a

       CALL PCSETC ('FC','|')

    to specify the use of vertical bars in place of colons, as in

       'A|S|2|N|/B|S|2|N|'

    I don't know what the equivalent NCL incantation might be ...
