---++ Description:

This subroutine counts the number of selected rows in a table widget. All parameters are required, the subroutine will cancel if any are missing.

&lt;count&gt; is the count of selected rows returned to you (Required). This must be PASSed with Share "Y" to return the value.

&lt;widget name&gt; is the name of the table widget (Required).

This is a quick way to determine how many rows the user has selected when they single or double click in a table widget.

This is a nice way to ensure that multiple rows aren&#39;t selected when you only want to process one record. A nicer future enhancement would be a field in the Widget file to allow or disallow multiple selections (WIDGET MULT ROWS OK?).
