The following applies to the names of programs, modules, variables, and all database objects (e.g. names of users, databases, tables or result tables):
The first character can be a letter or one of the characters '$', '#' or '@'. After that, letters, digits and '_','$','#','@' can follow. No difference is made between upper and lower cases.
The name of a program, a module or a database object can also be composed of arbitrary characters in which upper and lower cases are distinguished when the name is enclosed in double quotes.
Note:
On keyboards without the '@' character, the section sign may be used instead.
For all names, the first 18 characters are significant.
