- Microsoft Visual FoxPro for Macintosh, version 3.0b

SUMMARY
=======

There is no function available in Visual FoxPro for the Macintosh that provides
information on the amount of physical RAM on the machine. However, the Ram
selector of the FxGestalt()function in the FoxTools.cfm library provides
information on the amount of physical RAM installed on a machine.

MORE INFORMATION
================

The following code example returns the amount of physical RAM installed on the
machine. The function ignores any virtual memory. This code returns an integer
indicating the amount of physical RAM.

In the Command window or a program, enter the following lines of code:

     SET LIBRARY TO Home()+"foxtools.cfm"
     ram_amt=0
     i=FxGestalt("ram ",@ram_amt)
     ? INT(ram_amt/1024/1024)

Notice a space exists after the "Ram" selector in the FxGestalt function.
Omitting this space causes the function to fail and return a -1.

All the selectors of the FxGestalt function are four letters long. The Help file
states this fact in the Syntax section. The example in the FoxTools Help file,
however, is not quite clear on this point. Since the space character is not
easily seen in the example, it is easy to overlook it.
