The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

─────Concatenating Help Databases───────────────────────────────────────────
 
     The help database file produced by HELPMAKE can be concatenated
     with other help files by using operating-system commands.
 
     You can use the DOS or OS/2 COPY command to concatenate files. For
     example,
 
          COPY A.HLP /B + B.HLP /B  C.HLP /B
 
     concatenates B.HLP to the end of A.HLP and stores the result in
     C.HLP. Note the COPY /B option──this indicates that the files to
     be copied are binary files.
 
     When HELPMAKE creates a help database, it records the database
     name within the file. This internal file name is preserved when
     you concatenate or rename files.
 
     For example, if you create a help database file named APPLE.HLP
     and rename the file to ORANGE.HLP, the original name (APPLE.HLP)
     is still recorded in the database. If ORANGE.HLP is then
     concatenated to FRUIT.HLP, the original name (APPLE.HLP) still
     refers to a single database within the concatenated help file.
 
     When linking from one help database to another, you should use the
     internal database name. This allows you to link to a specific
     database within a help file containing several databases.
