Tool Command Language, 1988-today. A
dynamic programming language for Mac/
Unix/Windows computers. It can be considered as merging the heritages of Lisp, C, and Unix shells. With a very simple syntax Tcl makes it possible to implement a number of programming styles: functional,
object-oriented, stack-oriented, etc.
proc lrevert list {#-- revert a list in Tcl
set res {}
set n llength $list
while {$n>0} {lappend res
lindex $list incr n -1}
return $res
}
% lrevert {
foo bar grill} ;# testing Tcl
grill bar foo
