Sample Service Program

Updating the Service	Program
Because of the binder language,							the	service program		could be update
program		CVTHEXPGM		would	not	have to	be	re-compiled. For example, there ar
two ways to add a new procedure to								CVTTOHEX, depending on whether th
procedure			goes	into	the	existing	module		or into a new	one.
To	add a	new	procedure	to an	existing module		,	you	would:

1. Add the new procedure to the existing module.

2. Recompile the changed module.

3. Modify the		binder	language source to	handle	the interface associa
new	procedure. This		would involve adding	any	new expfortllowingstatements
the	existing	ones.

4. Recreate the service program using CRTSRVPGM.

To add	a new	procedure using		a	new module	,	you		would:
1. Create		a	module	object for		the		new	procedure.
2. Modify		the	binder		language	source		to handle the interface associa
new	procedure, as				mentioned	above.

3.Bind the new module to service program CVTTOHEX by re-creating the program.

With either method, new programs can access the new function. Since th exports are in the same order they can still be used by the exist it is necessary to also update the existing programs, they do not ha compiled.
