For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
List

Posted by kris6 (kris6), 6 September 2006
I have two lists, say a and b
set a {1 2 3}
set b {x y z}

I need output as {1 x 2 y 3 z}
Is there any TCL function which does that?

There's no function to merge two lists in that order - concat will join one list on after another, but that's NOT what you need!  I would do it with a for loop ...

Code:
set a {1 2 3}
set b {x y z}

for {set k 0} {$k < [llength $b]} {incr k} {
       lappend result [lindex $a $k]
       lappend result [lindex $b $k]
       }

puts $result
