PRELIMINARY

**************************************************************

**	Now that the data to be programmed is ready, the	**
**	programming algorithm is invoked. Note: Four parameters	**
**	must be initialized before calling the algorithm.	**

***********Next, program flash************
CALL	GPGMJ	;Program flash from buffer.

B	prg_done	;Else, No errors programming.

prg_error:

**********************************************************

**	If here, then an error occurred during programming.	**
**	In an actual application, the system takes some	**
**	action to indicate that service is required.	**

**********************************************************

B prg_error ;Error while programming.

prg_done:

**********************************************************

**If here, then flash has been successfully programmed. *
