NAMElappend − Append list elements onto a variable

---

SYNOPSISlappend varName ?value value value ...? .\}

---

DESCRIPTIONThis 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 does not 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.

---

EXAMPLEUsing 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
