Re: SXMACLIB

As well as I know it, though I wasn't following it much at the time, there
 was a long time when software wasn't considered copyrightable.
 

 We are so used to it being copyrightable now, that it is hard to
 imagine it ever being different.  

 

 I suspect partly it was that, at the time, each company's software
 only ran on their computers, so it didn't matter much.
 

 Well, for many years, computers were sold without software,
 or with very little.  OS/360 was close to the beginning of large amounts
 of software to go with a computer system.
 

 It takes a little while for the law to catch up with changes in
 technology.
