    SIC EXTENSION .SOMETHING

        controls the default macro extension used by commands  @  and  EDIT.
        This  default extension is program dependent: for all GAG softwares,
        it is the program name, while many user created applications use the
        generic default extension .PRO.
    SIC HELP PAGE | SCROLL | INDEX | CONTENT | MOSAIC | NETSCAPE

        controls whether the HELP command outputs  the  text  page  by  page
        (PAGE),  or continuously (SCROLL). SIC HELP INDEX indicates the HELP
        command should display the page referenced first in the index of the
        PostScript  documentation.  SIC  HELP  CONTENT  indicates  the  HELP
        command should display the page referenced first  in  the  table  of
        contents from the PostScript documentation. The last two options use
        the GhostView facility on X-Window terminals.

        SIC HELP MOSAIC or NETSCAPE indicate the HELP command  should  refer
        the  HTML  version  of  the  documentation  and  use the appropriate
        browser to display it.

    SIC Language\ ON or OFF

        LET command is compulsory. In FREE syntax, commands lines like
               A[I,J] = SIN((2*I+J)/PI)
        where A is a known  variable,  are  recognized  as  assignement  and
        automatically expanded to the equivalent FIXED syntax
               LET A[I,J] = SIN((2*I+J)/PI)
        Free syntax cannot be used for the LET /WHERE command.
