Tcl_PutEnv(3tcl) Tcl Library Procedures Tcl_PutEnv(3tcl)__________________________________________________________________________________________________________________________________________________NAME
Tcl_PutEnv - procedures to manipulate the environment
SYNOPSIS
#include <tcl.h>
int
Tcl_PutEnv(assignment)
ARGUMENTS
const char *assignment (in) Info about environment variable in the format "NAME=value". The assignment argument is in the system
encoding.
_________________________________________________________________DESCRIPTION
Tcl_PutEnv 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 putenv system call. All Tcl-based applications using putenv should redefine it to Tcl_PutEnv so that they
will interface properly to the Tcl runtime.

break(3tcl) Tcl Built-In Commands break(3tcl)__________________________________________________________________________________________________________________________________________________NAME
break - Abort looping command
SYNOPSIS
break
_________________________________________________________________DESCRIPTION
This command is typically invoked inside the body of a looping command such as for or foreach or while. It returns a TCL_BREAK code, which
causes a break exception to occur. The exception causes the current script to be aborted out to the innermost containing loop command,
which then aborts its execution and returns normally. Break exceptions are also handled in a few other situations, such as the catch com-
mand, Tk event bindings, and the outermost scripts of procedure bodies.
EXAMPLE
Print a line for each of the integers from 0 to 5:
for {set x 0} {$x<10} {incr x} {
if {$x > 5} {
break
}
puts "x is $x"
}
