[Gretl-users] String pointer?

2014-04-30 Thread Logan Kelly 
Hello,

Are pointers to strings allowed? (I am using 1.9.15cvs on Win7 64 bit) The 
following script:

function test(string *t)
t="Hello World"
end function
string MyTestString
test(&MyTestString)
print MyTestString

yields the following error

gretl version 1.9.15cvs
Current session: 2014-04-29 19:46

? function test(string *t)
> function test(string *t)
Unrecognized data type 'string *'

Error executing script: halting
> function test(string *t)

Please, look at the Gretl users' guide:

"13.4 Function programming details

Variables versus pointers

Series, scalar, and matrix arguments to functions can be passed in two 
ways: "as they are", or as
pointers."

There is no such a feature for strings.

Thanks. I have not gotten used to the existence of the hansel primer.

The statement in the user guide is not conclusive given that bundles are not 
listed and yet can be passed as pointers.

One more silly question, why are lists and strings excluded? (This is not 
important. Just curious.)
