[LA.pm] alternating...

[Peter Benjamin]

A case to try perl -d to see code execution order,
as I can not see what is wrong via visual inspection
and it worked for me with this initialization:

my @mem = (
"1",
"2",
"3",
"4",
"5",
"6",
"7",
);

I do suggest you avoid variable names that might conflict
with reserved words, as "$line" might do in some languages,
just on general principles.  Same with mem, which is an unix
command.

Post your test data for @mem would be good.

Starting $color as uninitialized is not wise, imo.

Also, try perl -w  and strict for more detailed error messages.

Trick: avoid \" inside of double quoted strings by using just '

-p
