Hello
I have been trying to get a handle on the 'for.' control command, using a
little program taken from a
Pascal book, of which I have written a script as follows:
load 'print'
humbug=: 3 : 0
for. >: i.3 do.
print 'We wish you a Merry Christmas'
end.
print 'And a Happy New Year!'
)
Here are the instructions, which I think are relevant, taken from the last
example of section 12.3.7 of 'Learning J':
Another variation is the pattern for. A do. B end. in which block B is executed
as many times as there are items of A.
However, when I run this program, all that results is a copy of the code.
What am I doing wrong?
Thanks in advance.
Charles
