TSR: Your local C:\ disk must contain a directory called "_SYS" and the directory must contain the help file(s) used by your application. In addition, this directory must contain JQBTAUS.HLP (common help file).
For RAM applications, help files should be placed in C:\_SYS.
For the applications in ROM, the application help file sare in the D:\_SYS directory. On the 100LX/200LX, help files to override those in ROM may be placed in C:\_SYS, with the same names as the applications they are overriding.
