( Update: Oh! you are trying to create symbolic reference. Read Why it's stupid to `use a variable as a variable name' for why that's unwise. Use a hash instead, and then you can use the hash slice I mention below. )

I don't know what you are trying to do, but I'll point out two problems with that statement.

• You are assigning an array to a scalar.

       ${@Fld}=@test; 
       ^       ^
       |       |
     scalar  array

  An array evaluated in scalar context returns its length, so the length of the array would be assigned.

• ${@Fld} doesn't make much sense. It looks like a dereference, but @Fld is not a reference. Since references are scalars, the dereference (${...}) expects a scalar value. @Fld evaluated in scalar context is its length, so ${@Fld} is ${2} aka $2.

Maybe you are looking for a hash slice?

my @test=(11,22,33,44);
my %Fld;
@Fld{'LCD','XCOORD','Y','Name'} = @test;
print($Fld{Y}, "\n");  # prints 33
