If the listing of a statement exceeds the maximum allowed length of a record for a
given file (e.g., 80 for terminals), the statement will be broken into multiple segments
(records/lines). The first n characters (where n is the maximum segment length) will
be contained in the first segment with each subsequent n characters up to the end of
the statement sent in subsequent segments. Each continuation segment will be
prefixed by the line number followed by a colon ":" and a space.
Note: If a semicolon (;) is used as the first character of a line, ProvideX will hide the
line from listings making it appear as if it did not exist. The line will execute correctly,
but it cannot be viewed via the LIST directive.
Coloured Syntax Displays
If the 'CS' system parameter is on, your listing will be displayed with a different
called COLOUR (or COLOR) that can be used to display or alter the current settings.
Type COLOUR or COLOR at a ProvideX prompt to display online help for this utility.
Highlighted Search Strings
parameter is on, the system will automatically highlight the search string when the
program is listed. For a description of the search utility syntax, refer to
