PERL Variable names, Significant Length

I'm new to PERL and i just wanted to ask how many are the significant initial characters in naming a variable in PERL. I know that a variable has a maximum name length of 255, but how many of these are significant.

In C for instance,
<quote>
63 significant initial characters in an internal identifier or a macro
name (each universal character name or extended source character is
considered a single character)
— 31 significant initial characters in an external identifier
< end quote>
