range

    Defines the boundaries of the search. If you do not specify
    a range, the SEARCH command searches the module most recently
    referenced with a SEARCH or TYPE command, from the line following
    the last line displayed to the end of the module. PCA can search
    only one module at a time. These boundaries may be defined with
    any of the following formats:

    modname                             Searches the entire specified
                                        module.
    [modname\]line-number               Searches the specified module
                                        from the specified line
                                        number to the end of the
                                        module.
    [modname\]line-number:line-number   Searches the inclusive
                                        interval between the two
                                        line numbers of the specified
                                        module.

 string

    Specifies the sequence of characters to search for in the source.
    If you do not specify a string, then the most recently specified
    search string is used. If the string contains spaces, tabs,
    commas or parentheses, then it must be delimited by either
    double or single quotation marks. If the string delimited by
    quotation marks has a quotation mark within it, the enclosed
    quotation mark must be expressed as two consecutive quotation
    marks (i.e. If the string delimited by single quotation marks
    has a single quote within it, the enclosed single quote must be
    expressed as two consecutive single quotes (e.g. '')). The search
    is case sensitive depending on the currently set language. If the
    string is not delimited, then the default range parameter must
    not be used and the string may not contain any blanks, tabs or
    semicolons.
