Various Small Tips and Tricks

[badidea]

How about a topic for various small "Tips and Tricks"? (If a bad idea form badidea, this topic can be ignored or deleted)

Small things that can prevent bugs or are neat tricks do to something. But where a whole new topic seems a bit much.
Things that might a obvious for some, things you learned to do over time, or are in the manual, but you never noticed.

I start with one. Don't do this (as I did a few minutes ago):

Code: Select all

dim as integer i
'code
for i = 0 to 9
	print i
	'code
next

Because you might end up with this:

Code: Select all

dim as integer i
for i = 0 to 9
	print i
	'code
	for i = 0 to 4
		'code
		print i;
	next
	print
next

Which makes your code hang or give unexpected results.
Instead use:

Code: Select all

for i as integer = 0 to 9
	print i
	'code
	for i as integer = 0 to 4
		'code
		print i;
	next
	print
next

Or use:

Code: Select all

dim as integer iBox, iCorner
for iBox = 0 to 9
	print iBox
	'code
	for iCorner = 0 to 3
		'code
		print iCorner;
	next
	print
next

From my point of view: things like that, can be posted in: "Beginners".
(Since it is only interesting, for Beginners.)

The problem is not so much to write and to post those snippets, but to find them. An unsorted assemblage is nearly useless.
