Yeah lets start the old begin end placement debate :-)
I use
If cond then
begin
dostuff
end
because of the old habit of finding the missing b/e in an editor that
couldn't check
but it gets messy with a block after else
If cond then
begin
dostuff1
end
esle
begin
dostuff2
end
so sometimes i use
If cond then
begin
dostuff1
end
esle begin
dostuff2
end
which lead me to the conclusion that I should
If cond then begin
dostuff1
end
esle begin
dostuff2
end
HTH (sarcasm)
