What's wrong with the following alternative:

a = iif( a<=0, 1, a)

For those of you that are not familiar with this, "IIF" is a logical
conversion function commonly found within other free format languages. It is
powerful, and very versatile. The syntax is as follows:

iif( condition, true_expression, false_expression)

Just a small example of how we can find better ways to do things if we take
the time to look at what has been done elsewhere.

Until you start nesting the suckers.
