Files for extending the Visual Tcl interpreter (/bin/vtcl). * vtcl.h * libvtcl.a * main.c The Visual Tcl interpreter can be extended with additional commands that you create. For example, you might want to add commands, written in C, that are specific to making C-based Sybase or Oracle SQL calls. Man pages are included that document the Tcl functions for extending the Tcl interpreter. Please read AppInit.3 and CrtCommand.3 to get started. SCO will eventually incorporate these man pages into its standard Visual Tcl documentation library. Please note that "vtcl.h" is equivalent to the "tcl.h" referenced in the man pages.
