Re: automatic & static storage in a subprocedure

["David Morris" <dmorris@xxxxxxxxxxxxx>]

Dave,

It depends.  They are static and global to the module.  It will be the same 
under the conditions you describe except when another procedure in the module 
is called and changes the indicators value between calls.  IE:  SUB_PROC_A sets 
on *IN01 then returns.  Then SUB_PROC_B in the same module is called which sets 
off *IN01.  Because the indicator is global when you call SUB_PROC_A it will be 
off.

Best practice is to avoid using indicators, possible on V4R2.  If you must use 
the indicator I would move the indicator to a static variable and move *IN01 to 
the variable immediately after *IN01 is used.  Then always refer to the 
variable.  I would also localize indicators wherever possible.  You can 
localize an indicator to by saving it to a  variable on entry and restoring it 
on exit. IE: Define a variable as LIKE(*INXX).  Eval that variable to be = 
*INXX on entry and use an eval *INXX = variable on exit.

On V4R2 you can avoid most indicator use with the new built in functions.  Use 
%EOF, %EQUAL, %FOUND, %OPEN, %ERROR, and %STATUS.  There is also a new 
operation extender "E" to be used to set the error status %ERROR.

Hi,
Are indicators that are used in a subprocedure stored in
static storage or automatic storage?

If I leave SUB_PROC_A  with  *IN01 = *ON,
and the activation group that SUB_PROC_A runs in
is a named activation group that is not (for the time being) deleted,
the next time I  CALLP  SUB_PROC_A, will *IN01 still = *ON?
