Peeklong returns the unsigned 32-bit integer stored at a given address. This value is represented in hexadecimal, but you may use the HexToDec XFCN provided in this stack to convert the value to a decimal if you wish.

A typical useage of peeklong would be:

                    put peeklong("411000") into temp

On the Mac Plus, this would put the value 4CDF0007 into the variable temp.

As an option, you may include a second parameter with the Peeklong XFCN. If peeklong detects a second parameter, it returns a 2-line result that consists of the longinteger stored at the given address in the first line and the next viable address (the original address+8) in the second line. This option provides a simple and effective way to use peeklong in a script to peek into a range of addresses. 

See the demo on this card for an example.  

The address provided to peeklong must be even or an error will result.
