Conventions

When using operators and functions, follow these rules for representing the data values:

• Enclose text strings within quotation marks.
• Type numbers without punctuation. (Numerals without quotation marks are numbers; numerals within quotation marks are text.) If you want to see $24.50 you would write this as 24.50 and just omit currency symbols.
• Insert field names without quotation marks, regardless of whether they represent string or numeric data.
