This procedure is typically invoked as the very first thing in the application's main program. .PP The result of \fBTcl_InitSubsystems\fR is the full Tcl version (e.g., \fB8.7.0+abcdef...abcdef.gcc-1002.utf16\fR). .PP \fBTcl_InitSubsystems\fR is very similar in use to \fBTcl_FindExecutable\fR. It can be used when Tcl is used as utility library, no other encodings than utf8, iso8859-1 or utf-16 are used, and no interest exists in the value of \fBinfo nameofexecutable\fR. The system encoding will not be extracted from the environment, but falls back to iso8859-1. .SH KEYWORDS binary, executable file
