lvarpush(TCL)


lvarpush -- insert string to specified list

Syntax

lvarpush var string [indexExpr]

Description

The lvarpush command pushes (inserts) string as an element in the list contained in the variable var. The element is inserted before position indexExpr in the list. If index is omitted, then 0 is assumed. If var does not exist, it is created.

If the expression indexExpr starts with the string ``end'', then ``end'' is replaced with the index of the last element in the list. With ``end'', the string is inserted before the last element. If the expression starts with ``len'', then ``len'' is replaced with the length of the list.
