O.K. - I run Perl on win2k - screen dumps follow:
C:\>PATH
PATH=C:\Perl\bin\;C:\Tcl\bin;......
C:\>perl -e "print qq~Hello\n~"
Hello
C:\>perl
print "hello\n"
hello
^C
C:\>
So, Perl works.
Now, I have some scripts (one of which is called 'example.pl' - the one from
the start of 'Learning Perl') in a directory called MyPerl on c:\
This script is:
#!perl
@lines = `c:\\Perl\\bin\\perldoc -u -f atan2`;
foreach (@lines) {
s/\w<([^>]+)>/\U$1/g;
print;
}
So to run this script.......
C:\>cd MyPerl
C:\MYPERL>example.pl
=over 8
=item atan2 Y,X
Returns the arctangent of Y/X in the range -PI to PI.
For the tangent operation, you may use the MATH::TRIG::TAN
function, or use the familiar relation:
sub tan { sin($_[0]) / cos($_[0]) }
=back
C:\MYPERL>
This scripts runs fine from the command window - remember that if you just
double click on a script from file manager, it will just fire up a command
window for long enough to run the script - you need to open a command window
(Start -> Run -> Command) and then change directory to where your script is
saved and then execute the script by typing its name (with extension). You
could also specify the full path to the script from the command prompt -
i.e. c:\MyPerl\example.pl
