I remember once getting an ANSI labeled tape from them but in EBCDIC and broke all our tools. I remember the ANSI format produced by OS/360. It faintly resembled real ANSI labels, but the text was encoded in 8 bit ASCII , an IBM invention that no one else ever used before or since. I think they took regular 7 bit ASCII and moved the top bit up one so, for example, A was encoded as 0x81 rather than 0x41 as in real ASCII. After that discovery, I switched back to IBM standard labels (IBM proprietary, in EBCDIC), or more usually, unlabeled since IBM didn t do useful label processing anyway. paul
