Kamal,
can you please attach the script?
I just copied it into a.pl and executed via:
perl a.pl
and it worked.
What does the error syntax message say?

my %var1 = (
user1 => "kamal"
user2 => "ahmed",
);

You are missing a comma after "kamal".

my $a = "hello"
print $a;

You are missing a semi-colon after "hello".

The script you show does NOT match the original scripts posted!

my %var1 = (
user1 => "kamal"
user2 => "ahmed",
);
print keys %var1;

Here you should have a comma after kamal, but not after ahmed.

***********************************
my $a = "hello"
print $a;

This misses the required semicolon after on the first line!

---------------------------
my %var1 = (
user1 => "kamal",
user2 => "ahmed"
);
print keys %var1;
-----------------------
my $a = "hello";
print $a;

No need to attach the script here.

'my' is a perl5 keyword, and I bet you have an old perl4 (/usr/contrib/bin) that prevails in your $PATH

# perl -v

should show it

just make sure (edit /etc/PATH) that /usr/contrib/bin is last in your $PATH

For #2:

add a ; after "hello"

Kamal;
a very quick check:
perl -e'my $a="hello";print $a'
Ensure that perl/lib is in your $PATH
Check what you are running with : which perl
Ours is in /usr/contrib/bin

your header states that you also have installed perl5, so as I said, move /usr/contrib/bin to the end of your $PATH

perl4 is dead!

# echo $PATH
# /usr/contrib/bin:/bin:/usr/local/bin:/usr/bin

for sh/ksh/bash:
# export PATH=/bin:/usr/local/bin:/usr/bin:/opt/perl/bin:/usr/contrib/bin
for tcsh/csh:
# setenv PATH /bin:/usr/local/bin:/usr/bin:/opt/perl/bin:/usr/contrib/bin

Be sure to change it in /etc/PATH too!

Enjoy, Have FUN! H.Merijn
