There may be nothing wrong with the syntax, but "transformations" will not
get executed until SPSS encounters a procedure, OR, an execute command if
you have no procedure immediately following the transformations. Execute
would probably only be needed after the end of the END REPEAT, but you can
force execution with multiple execute commands if you like.

The syntax you have shown has NO procedure listed.  Have you ever noticed
the message "execution pending" while running a program?  It's waiting for
something, like EXECUTE or a procedure, to trigger the running of the
"transformations".

HTH.  I really did like the days of syntax!
