RE: IBM Object naming rules

The IBM Knowledge Center would be a good place to start:

Naming a User-Created Object
To distinguish a user-created object from an IBM-supplied object, you
should not begin user-created object names with Q because the names of
all IBM-supplied objects (except commands) begin with Q. Although you
can use as many as 10 characters in CL object names, you might need to
use fewer characters to be consistent with the naming rules of the
particular high-level language that you are also using. Also, the
high-level language might not allow underscores in the naming rules. For
example, RPG limits file names to eight characters and does not allow
underscores.

Subject: IBM Object naming rules

Could someone point out an online reference for object naming rules
for the standard maximum ten character upper case alpha numeric object
names for files? I understand that hyphens are illegal, but
underscores are valid. What is the domain of valid characters?
