Hello janh,
yes, they are all genuine! I meant to explain them but ran out of time. They illustrate the range of parts of speech which we adapt to use as verbs.
"C is the result of oring A and B"
This means that A, B and C can only have the values 0 or 1, and C will be 1 if either A OR B is 1, otherwise C will be 0.
OR is therefore an operation like plus, minus etc. But I don't know what part of speech it is. In the sentence "A plus B equals C", what part of speech is "plus"? Anyway, it turns into the verb "to or", meaning to apply the OR operation to two values. Similarly, there is a verb "to and" meaning to apply the AND operation (C is 1 if both A and B are 1, otherwise C is 0).
"I'll grep around for that file..."
Verbification of a proper noun - grep is a computer program to find files and hence to grep means to look for.
"Are you going to GPL that software?"
Verbification of an acronym!! this sentence could have been expressed as "Are you going to release that software under the Gnu Public Licence?"
Here's an English example of adjectivisation of a verb, commonly used by software engineers
"Have you added the correct include files?"
include files being files that need to be included.
I must say, I'm with robinw on this one - if it's clear then use it! Why is English so globally successful? could it be because it is uncontrolled and constantly simplified and adapted? I'd hate to have an official version and language police telling us what we can and can't say. Incidentally, the French seem to have successfully got rid of le computer in favour of l'ordinateur, but everybody still seems to say le weekend.
In the industry that I work in, acronyms are endemic, and frequently end up as nouns, adjectives or verbs. I have a paper on my desk at this moment entitled "Ip in the Utran", which always makes me laugh. Internet Protocol in the Universal Mobile Telephone System Terrestrial Radio Access Network of course.
The Third Generation Partnership Project, which is the standards body for 3G mobile phones, issues a whole document of its acronyms for reference. My favourite one is OSPIHOSS = Octet Stream Protocol for Internet Hosted Octet Stream Service. I'm just goin' into town on ma ospihoss...
