My apologies for not providing any examples of the use of the set command; I'm glad Melissa did. The first computer I used was an IBM 1620, in 1967, so it's hard for me to remember not being able to read that sort of thing. 4K _core_, Fortran 2, etc. There's been a bit of change, except in technical writing styles.
