is this possible ?

[Eric]

is something like this possible in tcl ...

set dataList { {eval echo "my command"} dataItem1 dataItem2.....}

foreach data $dataList {
$dataList
}

knowing that that dataItem1 dataItem2 .... are all commands and that echo is
a command that needs to evalutaed... can you just use $dataList to get it to
run the eval command or how could you accomplish something like this?

lappend lst [list puts one]
lappend lst [list puts two]
lappend lst [list puts three]

foreach script $lst {
eval $script
}

Embedding the [eval] in $script is a bad idea.

With this though it will eval all one two and three commands .. i just would
like one of the list commands to be evaluated and the rest to be executed.

Executed like in "execute an external command" ? If so:

lappend lst $script_that_when_evaluated_returns_a_command
lappend lst $command_arg1 $command_arg2 $command_arg3

set command [namespace eval :: [lindex $lst 0]]
eval exec $command [lrange $lst 1 end]

example:

lappend lst {auto_execok ls}
lappend lst --size --kilobytes

set command [namespace eval :: [lindex $lst 0]]
set result [eval exec $command [lrange $lst 1 end]]

TCL evaluates scripts the global namespace.

Yep. Isn't Tcl fun? :-) Just follow the rules on Tcl.n and it works.
