mem function		function

Syntax
info = mem(expr)

Description
Specify a value expr to get information about the application's index$ array.
Old FB mem implementations returned information about available memory but OSX/macOS no longer support that approach, so mem's old options are gone.

expr	Value	Value returned by mem(expr)
indexID + _numElem	10-19	The element number of the highest element in this array that has been assigned a string, plus 1. Equals zero if no element has a string assigned to it. This number is also affected by the `index D` and `index I` statements.
