scalar

See the current Perl documentation for scalar.

Here is our local, out-dated (pre-5.6) version:


scalar - force a scalar context



scalar EXPR



Forces EXPR to be interpreted in scalar context and returns the value of EXPR.

    @counts = ( scalar @a, scalar @b, scalar @c );

There is no equivalent operator to force an expression to be interpolated in list context because it's in practice never needed. If you really wanted to do so, however, you could use the construction @{[ (some expression) ]}, but usually a simple (some expression) suffices.

[Eily]: hello muthusathish, we have many helps here
[muthusathish]: i have a perl based dll, how to decompile
[hippo]: :-D
[Eily]: you mean a dll where the SW was written in perl? That sounds unlikely
[muthusathish]: please help me regarding this
[hippo]: Easier just to go and look at the source, no?
[Eily]: mostly because perl isn't compiled in the usual sense of the meaning, you can't execute the opcodes directly, you need the perl engine
[muthusathish]: i dont have the environment too, but i need to get the logics so that i can re-wite
[Eily]: what makes you think your dll is "perl based" ?
[muthusathish]: i dont have source code too
