Clarify datatype for arguments to the Run function.

[karinsandraerika]

When compiling the schemas a comment is added for the Run function to describe the arguments needed. The abbreviations to describe the datatypes are internal and should be clarified.
E.g instead of ns (numeric scalar), cs, nv...
Use something like: bool | bool[] | bool[;]
char | char[] | char[;]
etc.
