What does this correction in note 2371726

[Former Member]

Hello Experts!

Would help me understand with below correction of note 2371726.

I think it is pretty simple but i have few querries and im new to abap codes.

Does the below correction mean that

directory names that include [A-Z a-z 0-9] and [ _ ] will be allowed to create.

For example, below directories are ok.

1. Example_directory , example_directory123,

Below directory names will not be alowed to create.

1. Example123! 2. exampledir!%

Plus my question is will below directories allowed to create?

1. Exampledirectory 2. Exampledir_ 3. _exampledir

(directory names that does not include "_" or the "_" is in the front or last.

For ABAP specific regexes it is much better to use program DEMO_REGEX[_TOY].
