RE: MAIN and LR -- RPG400-L

Most of my local variables are defined as Static and the first thing the procedures do (in freeform) is initializes the Static variables (unless of course I intend on the static value being persistent across multiple calls to the procedure).

Put all the variables you want to initialize in a data structure and do a "Reset" at the top of your code. This sets them all back to their initialized values, does it not?

Is there any real difference or code/time savings by doing a D spec

D fielda 30a automatic

versus

/free
clear fielda
/end-free

in your main procedure.

I like the idea. Provide a keyword AUTOMATIC that could be used only on a global variable and would initialize every time the program was called.

Yes, but only the first time, if the variable is global, that a

every time you call a program or module it should execute the
initialize logic for a global variable if the variable has a INZ
keyword on the variable.

Not even!!!

I have many API-type programs that get called repeatedly and return
with *INLR off. If the global variables were reinitialized (even if
it was limited to those with an explicit INZ), many of those programs
would stop working properly.

The rule of the compiler is that global variables are static,
regardless of whether or not there is an explicit INZ. Changing that
rule would be a major issue for many people.

To get your behavior there would need to be an enhancement to allow
global variables to be specified as AUTOMATIC. If that were added, I
would expect those variables to be initialized on every call, even if
they don't have an explicit INZ.

I have to chuckle when I read that sig, Ken. And I agree 100% with

your

assessment about only changing the rules with an AUTOMATIC flag.
However, many might argue that I am not right in my mind, so there you

go.
