concat(1T) Tcl Built-In Commands concat(1T)__________________________________________________________________________________________________________________________________________________NAME
concat - Join lists together
SYNOPSIS
concat ?arg arg ...?
_________________________________________________________________DESCRIPTION
This command joins each of its arguments together with spaces after trimming leading and trailing white-space from each of them. If all
the arguments are lists, this has the same effect as concatenating them into a single list. It permits any number of arguments; if no args
are supplied, the result is an empty string.
EXAMPLES
Although concat will concatenate lists (so the command:
concat a b {c d e} {f {g h}}
will return "a b c d e f {g h}" as its result), it will also concatenate things that are not lists, and hence the command:
concat " a b {c " d " e} f"
will return "a b {c d e} f" as its result.
Note that the concatenation does not remove spaces from the middle of its arguments, so the command:
concat "a b c" { d e f }
will return "a b c d e f" (i.e. with three spaces between the a, the b and the c).

append(1T) Tcl Built-In Commands append(1T)__________________________________________________________________________________________________________________________________________________NAME
append - Append to variable
SYNOPSIS
append varName ?value value value ...?
_________________________________________________________________DESCRIPTION
Append all of the value arguments to the current value of variable varName. If varName doesn't exist, it is given a value equal to the
concatenation of all the value arguments. The result of this command is the new value stored in variable varName. This command provides
an efficient way to build up long variables incrementally. For example, ``append a $b'' is much more efficient than ``set a $a$b'' if $a
is long.
EXAMPLE
Building a string of comma-separated numbers piecemeal using a loop.
set var 0
for {set i 1} {$i<=10} {incr i} {
append var "," $i
}
puts $var
# Prints 0,1,2,3,4,5,6,7,8,9,10
