There's a pervasive ambiguous and careless usage in this area.
One of my favorite (not!) examples is:
Title: z/OS V1R7.0 MVS Assembler Services Reference ABE-HSP
Document Number: SA22-7606-07
91.0 ENQ -- Request Control of a Serially Reusable Resource
* 91.1 Description
91.1.8 Parameters
qname addr
Specifies the address of an 8-character name. The name can contain
any valid
hexadecimal character. ...
OK. The adjectives "valid" and "hexadecimal" appear to be restrictive -- It's
pretty hard to expand the scope of "any". I'd infer that some characters are
not valid, and the qname can not contain them. Where are the valid characters
enumerated? Are they the same as the characters called "valid" in the JCL
manuals? And does the use of "hexadecimal" imply that the only characters
which the qname may contain are '0', '1', '2', '3', '4', '5', '6', '7', '8',
'9', 'A', 'B', 'C', 'D', 'E', and 'F'? Or that the addressed qname must be
expressed in assembler language as a hexadecimal self-defining term?
The meaning would be clearer if the two adjectives were omitted and it
simply said "any character".
