Several &NDB verbs use a free-form text syntax.
For more information about the &NDBSCAN verb syntax, see the Network Control Language Reference Guide.
When processing the free-form text, certain characters, for example, '(', ',' and ')', act as delimiters. If the data value contains one of these characters, it could cause a syntax error, and will not be preserved.
To prevent this, data values can be quoted, using either single (') or double (”) quotes. If the data contains the selected quote character, two of that character must be used.
The &NDBQUOTE built-in function automatically quotes the data when required. It knows the characters that require quoting, and picks single or double quotes as required. It also handles doubling of embedded quotes.
