static void treatDirectiveLine(SimulaScanner scanner,
 String id,
 String arg)

Treat a directive line.

Parameters:

scanner - the scanner

insert

private static void insert(SimulaScanner scanner,
 String fileName)

%INSERT file-name

Will cause the compiler to include the indicated file at this place in the source input stream. INSERT may occur in the included file. In contrast to COPY, the included lines are not counted (they will all be numbered with the line number of the line containing the outermost INSERT). Furthermore, if the source is being listed, listing is turned off during the inclusion and turned on again when reading continues after this directive.

Parameters:

scanner - the SimulaScanner

fileName - the file to insert

page

private static void page()

%PAGE

Will cause the compiler to change to a new page in the listing file. If the page heading (as defined by %TITLE, see below) is non-empty, it will be printed on top of the new page.

setOption

private static void setOption()

%OPTION name value

Will set compiler switch 'name' to the value 'value'. The facility is intended for compiler maitenance, and is not explained further.

%SPORT ON / OFF

Enables/disables special S-Port Simula features, such as inclusion of the S-Port Library.
