!html_name filetypes

The following  file types  are used  in connection  with the  hypertext
system:

!begin_xlist [*.HLP, *.TXT, *]
!index STG
!item [*.STG]
    Files of this type  contain the source text  for a hypertext,  i.e.
    they serve as input files for the HCP; they belong to the group  of
    ASCII files.

!index HYP
!item  [*.HYP]
    Files of this type contain a hypertext; they are created by the HCP
    and read by ST-Guide.

!index REF
!item [*.REF]
    Files of  this  type  contain  reference  tables  to  one  or  more
    hypertexts; these files are also  produced by the HCP, but RefLink
    can also create them (by extraction). Optionally, with '+z' the HCP
    will  create  such  a  file  for  every  hypertext,  which   (again
    optionally,'+zz') will  also  be  included in  the  main  reference
    (usually (!file [ALL.REF])).

    The inclusion of such files in the main reference can however  also
    be be undertaken by RefLink/RefCheck.
 
    These files can be read by  the RefLink, the HCP and in  particular
    by  the  ST-Guide:  this  uses the  reference-files  for   finding
    references which  were  passed  by a  PureC-routine  and  also  for
    searching in the REF file 'manually' via a search dialog.

!index SCR
!index TXT
!item [*.SCR, *.TXT]
    If files  using  one  of  these extensions  were  produced  by  the
    programs HELP_RC or HELPDISK then they contain a source text for  a
    hypertext in  PureC  format. Files  produced  in this  way  can  be
    converted with PC-Conv into  an *.STG  file with  a  corresponding
    format, so that the HCP can translate them afterwards.

!index HLP
!index TXT
!item [*.HLP, *.TXT, *]
    If files  with  this extension  belong  to a  'hypertext'  for  the
    1stGuide program, then they  contain a portion  of the source  text
    for a 1stGuide hypertext. These files can be converted with 1stConv
    to an  *.STG file  in  corresponding format  so  that the  HCP  can
    translate them afterwards.

!item [*.H]
    Files with  this  extension contain  C  source-text. If  they  were
    created by a resource editor, then they can be read and interpreted
    by the HCP via @include so that  they can be used easily to  create
    documentation for the use of dialog boxes.

!index RSC
!item [*.RSC]
    Files with this extension contain menus, dialogs, alert boxes etc. 
    and are created by  resource editors. Though  such files cannot  be
    displayed directly  by  ST-Guide,  they can  be  incorporated  into
    hypertexts with  the  link command  and  displayed and  edited  'as
    dialogs'.
