Styling Text with Calculations
In previous versions of FileMaker, you could only format a calculated text field with a single style. A workaround for this limitation required so much effort that you only did so if it was critically important. In FileMaker Pro 7, you can use the Text functions to easily mix type attributescolor, font, style, and sizewithin the same calculated field.Using the calculated field Label we created in "Formatting Labels or Envelopes" on page 64, we can use the Text functions to make the recipients name appear in boldface (Figure 4.62).
Figure 4.62. The TextStyleAdd function can change the style of parts of a calculation field.

TipsBe careful when selecting a text color when you format text in a calculated field. The function allows you to select only RGB colors. Some RGB colors cant be reproduced accurately by a color printer.Changing a text style is not always the same as selecting the true bold or italic weight of the font you are using. If you want to use a fonts real italic, use TextFont instead of TextStyleAdd, and type the real typeface name (like Baskerville Bold Italic) in the FontName parameter.
