Alan did not answer hastily. From IBM Corporate Standard C-S 3-8010-003, 1998, "Volume Labels for Storage Devices": "This field may contain from one to six alphabetic and/or numeric characters. If the volume identifier is less than six characters, it is left-justified and the remainder is padded with spaces. On both input and output, the system must check this field against the value supplied by the user. The content is permanently assigned by the installation to identify this volume, and is entered at label creation. Note: Some existing systems accept a wider character set than is permitted here, if the characters are specified within enclosing apostrophes. Some programs to which this standard is applicable must maintain compatibility with these systems and are therefore permitted this specific additional latitude." The standard defines "alphabetic" as A-Z (actually, A, B, C, D, etc. to avoid confusion) and "numeric" as 0-9. So, our existing labeling programs that allow blanks in the middle of labels (very annoying) and characters that aren't the same in all code pages (@ is one) are permitted under the grandfather clause, but they aren't compliant.
