Perhaps it is not clear to Martin that "well-written" SPAD code should
look like this?
j: Integer
for i in 1..5 repeat
j := i^2
output(i::OutputForm)$OutputPackage
output(j::OutputForm)$OutputPackage
with j defined in the scope where it is used. See:

I think Gaby's change to require the definition to occur in the proper
scope is a good one.
