How to get the return code of subroutines executed as standalone as command line in Perl ?
How to do I get the return code of a subroutine in a perl module if invoke the subroutine as standalone,
I have an module say TestExit.pm and in that i have a subroutine say myTest() which is returns 12, if i were to call the subroutine from
command line like
CASE:1 ( Without an explict exit in END routine )
The above statement doesnot give me the return value of the subroutine ( which is 12 ) I get exit code as 0
Where as if I explicity do an exit in the END routine I am able to get the return code properly
Case2: ( With an explict an exit in END )
Is there a way to pass an argument to the module or Is there a trick to get the exit code without modifying the END routing to an explict exit,
END routine exit is commented to get to match the case 1
TestExit.pm

I know how to get the returning code of a function but wonder if I can combine the follwoing two lines into one:
e.g.:
#!/bin/shell
...
#line 1
MyFunction arg1 arg 2
#line 2
rec=$? #this will be evaluated later
....
like in c/c++, we'd write one line:
rec=MyFunction(arg1, arg 2)

ppi::statement::sub
PPI::Statement::Sub(3pm) User Contributed Perl Documentation PPI::Statement::Sub(3pm)NAME
PPI::Statement::Sub - Subroutine declaration
INHERITANCE
PPI::Statement::Sub
isa PPI::Statement
isa PPI::Node
isa PPI::Element
DESCRIPTION
Except for the special BEGIN, CHECK, UNITCHECK, INIT, and END subroutines (which are part of PPI::Statement::Scheduled) all subroutine
declarations are lexed as a PPI::Statement::Sub object.
Primarily, this means all of the various "sub foo {}" statements, but also forward declarations such as "sub foo;" or "sub foo($);". It
does not include anonymous subroutines, as these are merely part of a normal statement.
METHODS
"PPI::Statement::Sub" has a number of methods in addition to the standard PPI::Statement, PPI::Node and PPI::Element methods.
name
The "name" method returns the name of the subroutine being declared.
In some rare cases such as a naked "sub" at the end of the file, this may return false.
prototype
If it has one, the "prototype" method returns the subroutine's prototype. It is returned in the same format as "prototype" in
PPI::Token::Prototype, cleaned and removed from its brackets.
Returns false if the subroutine does not define a prototype
block
With its name and implementation shared with PPI::Statement::Scheduled, the "block" method finds and returns the actual Structure object of
the code block for this subroutine.
Returns false if this is a forward declaration, or otherwise does not have a code block.
forward
The "forward" method returns true if the subroutine declaration is a forward declaration.
That is, it returns false if the subroutine has a code block, or true if it does not.
reserved
The "reserved" method provides a convenience method for checking to see if this is a special reserved subroutine. It does not check against
any particular list of reserved sub names, but just returns true if the name is all uppercase, as defined in perlsub.
Note that in the case of BEGIN, CHECK, UNITCHECK, INIT and END, these will be defined as PPI::Statement::Scheduled objects, not
subroutines.
Returns true if it is a special reserved subroutine, or false if not.
TO DO
- Write unit tests for this package
