Syntax to increment variable names in repeat loop

[Nonsanity]

Arrays are the way to go there, but if you really do need to work with
constructed variable names, do is probably the only way to set such a value.
The following code clip shows how you can get the value of a constructed
variable name:

put 111 into var1
put 222 into var2
put 2 into whichVar
put merge( "[[var" & whichVar & "]]" ) into msg
