[Novalug] Fill in the blanks?

[jecottrell3 at comcast.net]

If I could design my own Interview questions, one of them would be "Go draw the ascii chart on the board.

Now the special chars can obviously drive one bonkers, but I would expect people to know that.

Control chars are 00..1F, and the values of \b, \t, \n, \v, \f, \r, \e, and DEL.

Space is 20
0..9 are 30..39, A-Z = 41..5a, a-z = 61..7a
The next easiest are the [\]^_ sequence after A-Z being 5b-5f
and the corresponding {|}~ DEL sequence after a-z being 7b-7f.
Then @ = 40 and ` = 60. The sequence after the numbers is :;<=>? = 3a=3f.

Those who remember bit-pairing terminals will know that the shifted numbers are 21-2a.
The actual sequence is !"#$%^'() followed by *+,-./ being 21-2f.

My gut feeling is that most True Wizards actually know this, along with the names of the control chars, and the ANSI escape sequences, at least the major ones.

Then again, maybe it's just me, or maybe it's just that I've been around so long and wrote a bunch of low-level stuff.

P.S. Yes, I was referring to the $ key, not the ASCII table, but any mnemonic you can make up is good...and you should definitely look for them yourself!

Ahh, mucho better.  I was wondering why Jim might expect
today's users to be familiar with the ASCII chart.  :)
