The string is in native format. .BE .SH DESCRIPTION .PP \fBTcl_PutEnv\fR sets an environment variable. The information is passed in a single string of the form NAME=value. This procedure is intended to be a stand-in for the UNIX \fBputenv\fR system call. All tcl-based applications using \fBputenv\fR should redefine it to \fBTcl_PutEnv\fR so that they will interface properly to the Tcl runtime. .SH KEYWORDS environment, variable
