In other languages, I can place a beep in the code to see if
program execution passed through a specific area of the code.
This does not work with the following example. I was told to use
warn "something"; &
print STDERR __line__; . I don't seem to be able to use them to
advantage.
In the following program I wish to learn how to use them to see
if execution flow passed through CCC.
#!/perl/bin/perl -w
use CGI::Carp qw(carpout fatalsToBrowser); # sends errors to
browzer
use strict;
use CGI qw(:standard);
#main part of the program
AAA();
BBB();
CCC();
#end of main part of program
#=========================================================
sub AAA()
{print "\07";} # beeps don't work
#=========================================================
sub BBB(){
print header(), start_html("1"); # program won't
work w/o this line
print end_html(); # program won't
work w/o this line
}
#=========================================================
sub CCC()
{
warn "something"; #?
#print STDERR __line__; #?
}
