NAME
lappend - Append list elements onto a variable SYNOPSIS
lappend varName ?value value value ...? _________________________________________________________________ DESCRIPTION
This command treats the variable given by varName as a list and appends each of the value arguments to that list as a separate element, with spaces between elements. If varName doesn't exist, it is created as a list with elements given by the value arguments. Lappend is similar to append except that the values are appended as list elements rather than raw text. This command provides a relatively efficient way to build up large lists. For example, ``lappend a $b'' is much more efficient than ``set a [concat $a [list $b]]'' when $a is long. EXAMPLE
Using lappend to build up a list of numbers. % set var 1 1 % lappend var 2 1 2 % lappend var 3 4 5 1 2 3 4 5 SEE ALSO

NAME
lindex - Retrieve an element from a list SYNOPSIS
lindex list ?index...? _________________________________________________________________ DESCRIPTION
The lindex command accepts a parameter, list, which it treats as a Tcl list. It also accepts zero or more indices into the list. The | indices may be presented either consecutively on the command line, or grouped in a Tcl list and presented as a single argument. | If no indices are presented, the command takes the form: | lindex list | or | lindex list {} | In this case, the return value of lindex is simply the value of the list parameter. | When presented with a single index, the lindex command treats list as a Tcl list and returns the index'th element from it (0 refers to the first element of the list). In extracting the element, lindex observes the same rules concerning braces and quotes and backslashes as the Tcl command interpreter; however, variable substitution and command substitution do not occur. If index is negative or greater than or equal to the number of elements in value, then an empty string is returned. If index has the value end, it refers to the last element in the list, and end-integer refers to the last element in the list minus the specified integer offset. If additional index arguments are supplied, then each argument is used in turn to select an element from the previous indexing operation, | allowing the script to select elements from sublists. The command, | lindex $a 1 2 3 | or | lindex $a {1 2 3} | is synonymous with | lindex [lindex [lindex $a 1] 2] 3 | EXAMPLES
| lindex {a b c} => a b c | lindex {a b c} {} => a b c | lindex {a b c} 0 => a | lindex {a b c} 2 => c | lindex {a b c} end => c | lindex {a b c} end-1 => b | lindex {{a b c} {d e f} {g h i}} 2 1 => h | lindex {{a b c} {d e f} {g h i}} {2 1} => h | lindex {{{a b} {c d}} {{e f} {g h}}} 1 1 0 => g | lindex {{{a b} {c d}} {{e f} {g h}}} {1 1 0} => g | SEE ALSO
