Many years ago, I was initially perplexed by the OS commands and their abbreviations. A lot of them were abbreviated to their initial letter
S start R reply C cancel D display L log M mount U unload V vary W writelog So far, so good. But there were others. F Modify N Define (MFT partitions) P Stop T set E reset I switch K control Z halt I tried to develop a set of 'rules' that covered this, based on the sequence in which the commands were specified. My theory is almost certainly wrong, but I found it whiled away the time in the machine room waiting for a channel check on a 2821 killing MFII R17 (over 2 days before it hit...) The above satisfied the following rules. 1 The first 'unreserved' letter in the command is its abbreviation. 2 The letter 'o' is not allowed. 3 Start was specified before Stop, Set and Switch. 4 Reply was specified before Reset 5 Reset was specified before Set. 6 Set was specified before Stop 7 Writelog was specified before Switch. 8 Modify was specified after Mount, Switch and Display. 9 Define was specified after Display, Reset, Modify and Switch 10 Control was specified after Cancel, Define, Set, Reply and Log 11 Halt just did not conform! I am sure someone knows a better scheme - and no doubt will tell us all!! MKB
