problem and error writing a command

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I am having trouble writing commands for the following commands and running into the following problem and error.Can anyone advise?

1.$cmd = [  qw(p4 submit -d $options{des} -f submitunchanged -i)  ];
run3($cmd, \$stdin, \$stdout, \$stderr); 
print "\n$stderr\n";

Problem:-Not deciphering $options{des}

$cmd = [  qw(p4 tag -l TEST_$options{r}_$dat $options{v})  ];
run3($cmd, \$stdin, \$stdout, \$stderr); 
print "\n$stderr\n";

Error:-$options{v} - no such file(s).

The following commands work using system though


system qq(p4 tag -l TEST_"$options{r}"_$date $options{v});

qw() doesn't interpolate, therefore $options{des} will be treated as a literal string. Use the following if you really want each element as a list instead of a single string like if you used qq{}. `$cmd = [ qw(p4 submit -d), $options{des}, qw(-f submitunchanged -i) +];` [download]	[reply] [d/l]

I figured out for the step 1,but for step2 I am having trouble figuring out...getting the below syntax error...Please advise `$cmd = [ qw(p4 tag -l ), TEST_$options{r}_$date, $options{v} ]; run3($cmd, \$stdin, \$stdout, \$stderr); print "\n$stderr\n";` [download] `syntax error at perl.pl line 197, near "$options{r" Execution of perl.pl aborted due to compilation errors.` [download]	[reply] [d/l] [select]

qw() is not qq(). It doesn't interpolate.	[reply]
