may not have line breaks, but
which we want to fit within
a specified character width
(between margins).
Function definition: (Copy & paste into FileMaker's Edit Custom Function window)
This is a function that uses a recursive routine to re-format a supplied block of text so that it falls within a specified margin width - ie it ensures that there is a line break before the spcified number of characters is reached on each line.
If the input text contains paragraphs which are separated by double carriage returns, these are preserved in the text that is returned.
If the input text contains no carriage returns, they will be inserted at the appropriate positions so that the text wraps within the defined text block size.
If the input text already contains carriage returns to mark hard line breaks they will be re-positioned to conform to the new specified margin width.
Note that the results may be variable depending on the font used: proportional-spaced fonts, since they do not adhere to a fixed character width, may exhibit more variability in the result than one would see with a mono-spaced font.
