Two solutions of 38 characters:

#        1         2         3
#2345678901234567890123456789012345678

perl -le'print+(H,T)[rand 2]for a..gr'

perl -le'print 1<rand 2?H:T for a..gr'

[redsquirrel]

Using your second example, you can take the score down to 37 like this:

perl -le'print+rand>.5?H:T for a..gr'

Can someone explain that "a..gr" thing to me please?

I'm baffled.

Same as 1..200, really ;)

Basically you just use letters instead of numbers.

a..z yields the 26 characters of the alphabet,
a..az yields those and another 26 prefixed with a
a..bz yields those and another 26 prefixed with b
and so on. Same system, more "numbers" ...

Incidentally a..gr yields 7*26 + 18 "numbers".

update : as crazyinsomniac pointed out, the range-operator is discussed in more detail in perlman:perlop.
