RE: what is a loop?

Hi Yanti,

A loop is basically just a set of statements that run until a condition is set.

For example:

i=0

if i <= 10

do something
i++

The above is pseudocode for a loop, this loop will do something until i reaches 10.

Hope this helps
Tracy

Access tip:

Choosing data types in Access

Not sure which data type to use for your Access fields? Here are some guidelines to help you choose a data type to assign to a field.

- The Text data type can accept up to 255 characters. For information that will be recorded in paragraphs, use Memo.

- Also use Text for numbers that aren't going to be used in calculations, e.g. phone numbers.

- Use the Currency data type for monetary amounts.

- Use Date/Time for dates.

- Most other numbers can use the Number data type, but the Field Size property may have to be altered.

- For fields that have only two alternatives (yes, no) use Yes/No data type. If there is likely to be a third entry option (e.g. maybe or don't know) use Text instead.
