NAME

       concat - Join lists together

SYNOPSIS

       concat ?arg arg ...?
_________________________________________________________________

DESCRIPTION

       This  command  treats  each argument as a list and concatenates them into a single list.  It also eliminates leading and trailing spaces in
       the arg's and adds a single separator space between arg's.  It permits any number of arguments.	For example, the command
	      concat a b {c d e} {f {g h}}
       will return
	      a b c d e f {g h}
       as its result.

       If no args are supplied, the result is an empty string.

SEE ALSO

       append(n), eval(n)

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, flattening them in the process (so giving the following interactive session):

	      % concat a b {c d e} {f {g h}}
	      a b c d e f {g h}

       it will also concatenate things that are not lists, as can be seen from this session:

	      % concat " a b {c   " d "  e} f"
	      a b {c d e} f

       Note also that the concatenation does not remove spaces from the middle of values, as can be seen here:

	      % concat "a   b	c" { d e f }
	      a   b   c d e f

       (i.e., there are three spaces between each of the a, the b and the c).
