Hi all,
I have just discovered the CLIKE generic type and am extremely happy to have a type that will allow me to accept all character type data via a parameter, however, I am experiencing unexpected behavior with empty strings. When I declare a string, clear it, and pass it to my method, it does indeed pass as an empty string, however, when I pass a literal empty string (''), it is passed as a single character. Also, if the parameter is optional and I do not specify it at all, it is passed as a single character, whether I specify the default value as a literal empty string or do not specify a default at all. Is this really the way CLIKE is supposed to work? This is absolutely not what I would expect.
To be clear, here is some example code:
The following passes an empty string correctly when the parameter is defined as a CLIKE:
data lv_str type string. clear lv_str. object->method( parameter = lv_str ).
The following, however, passes a single character:
object->method( parameter = '' ).
Thanks for any insight,
-Chris
