====== DNEXT() ======
Retuen none are available. 

**Example:**  

		println "The next available dbase file channel is ",DNEXT()

`DNEXT` was created in order to better support code libraries made possible by functions and procedures. File channel numbers can now be determined at runtime.  

**CAUTION!** Until you actually OPEN a file DNEXT will return the same value over and over.  
`chan1 = DNEXT() chan2 = DNEXT()`  WRONG! chan1 will equal chan2  

**another gotcha:** `FOPEN DNEXT(),...`  
There is no way to determine what channel was used to open the file!  
Here's an example of how it should be used:  

		chan1 = DNEXT() FOPEN   chan1,...  
		chan2 = DNEXT() FOPEN   chan2,...
