[lindex $arg 0] returns the first element in $arg, but its a list, so to turn it into a string change it to [lindex [split $arg] 0]

[lrange $arg 0 end] returns the whole line in $arg (from first letter to last letter, its also a list. to turn it into a string change it to [join [lrange $arg 0 end]]

lindex and lrange are list commands, and do not work well on strings.

Use "split" to covert the string to a list first.

Second, lindex returns a single element from a list. As such, if you split using spaces, then you don't get and spaces in return.

lrange returns a list in the form of a range of list elements. If you need the space back after, convert it to a string using "join".

You would have to show an example if this doesn't help.

hmm i got a string ..? and that string contains spaces but once i use lindex or lrange the string the spaces are lost so how do i use lindex or lrange without lossing spaces ? or any other char ?
