Please do not add FONT and SIZE tags to every line in your postings (especially inside CODE tags). The constant width font used by CODE tags makes spacing and text clear in code segments, sample input, and sample output. Overriding the CODE tag font and reducing the size of the text makes it harder to interpret these key elements of any issues you may have.

lassign
lassign(n) Tcl Built-In Commands lassign(n)
__________________________________________________________________________________________________________________________________________________NAME
lassign - Assign list elements to variables
SYNOPSIS
lassign list varName ?varName ...?
_________________________________________________________________DESCRIPTION
This command treats the value list as a list and assigns successive elements from that list to the variables given by the varName arguments
in order. If there are more variable names than list elements, the remaining variables are set to the empty string. If there are more
list elements than variables, a list of unassigned elements is returned.
EXAMPLES
An illustration of how multiple assignment works, and what happens when there are either too few or too many elements.
lassign {a b c} x y z ;# Empty return
puts $x ;# Prints "a"
puts $y ;# Prints "b"
puts $z ;# Prints "c"
lassign {d e} x y z ;# Empty return
puts $x ;# Prints "d"
puts $y ;# Prints "e"
puts $z ;# Prints ""
lassign {f g h i} x y ;# Returns "h i"
puts $x ;# Prints "f"
puts $y ;# Prints "g"
The lassign command has other uses. It can be used to create the analogue of the "shift" command in many shell languages like this:
set ::argv [lassign $::argv argumentToReadOff]
