Changing something toupper?

[Danko]

How can I change second toupper before i write/echo/whatever to file/chan when using this?

Code: Select all

foreach {first second} [split $arg] {break} 

or

Code: Select all

set first [lindex [split $arg] 1]
set second [lindex [split $arg] 2] 

(I belive the first one is faster code than the last one, correct?)

To convert second to topupper

Code: Select all

set second [string toupper $second]

And

Code: Select all

set first [lindex [split $arg] 1]
set second [lindex [split $arg] 2]

is different than

Code: Select all

foreach {first second} [split $arg] {break}

since the 2nd code takes the first and second words while the 1st takes the second and the third words. You need to start with index 0, so first is [lindex [split $arg] 0] and second is [lindex [split $arg] 1].
