USING(templateString, numericExpression)

This function formats numericExpression as a string using templateString.  The rules for the format are similar to those in Microsoft BASIC's PRINT USING statement,  but since using( ) is a function, it can be used as part of a larger BASIC expression instead of immediate output only.  The template string consists of the character "#" to indicate placement for numerals, and a single dot "." to indicate placement for the decimal point.  The template string must be contained within double quotation marks.  If there are more digits contained in a number than allowed for by the template string, the digits will be truncated to match the template.

A template string looks like this:

amount$ = using("######.##", 1234.56)
