Well, I am landing from C and this is all so intriguing, but at this time I'd like to load part of the file(binary) as array of chars. Like: read(FILE,$s,$I,$J); @s=split//, $s; however, It seems to me that much computer power are used in vain. Is there any other way that does the job directly without string variable $s?
