Description:

This subroutine converts a field containing HTML tags and encodings into plain APPX text. All parameters are required, if any are missing the subroutine will CANCEL.

<text> returns the converted HTML (Required). This must be PASSed with Share "Y" to return the value.

<HTML> is the HTML data you want converted (Required).

This routine will first convert any <br /> tags to chr(182), strip all remaining HTML tags, then convert any HTML entites into their ISO-8859-15 single byte equivalents, ie, ? becomes the paragraph symbol (chr(182)), etc. Entities that can't be converted will be changed to a space.

If <text> is too small to contain the converted text, --- .CONVERT HTML TO TEXT will contain 'Data was truncated'.
