If the first character of @{$memoryfile}[0] or (||) @{$memoryfile}[1] is not a printable character then log a error message and returns -1 value.

No. If *any* character.

And what's with "(||)"?

[ysth]

He's explaining that "||" means "or".

Also I feel LogMess must be some subroutine somewhere in the code, which accepts two arguments.

Close... The caret character (^) is a negation operator inside a character class here. Outside the character class, it would indeed be an anchor to the start of the string.
