Thank you RudiC for the updated code, sadly, one cant double thank in such situations.

So what i have now is this, with these questions:
Code:
	ln10=log(10)	# What is this for?
	#print ln10	## 2.30259

Really, i can make no sense of it, maybe i'm too focused on the number?

Code:
	# Again what for is ln10 used here and XP prepared for? And what is done anwyay?
	XP=int(log(NBR)/ln10/3)
	# print XP # = 1 or 0

Well i understand the 'order' of the math i guess, make a LOG-number from the passed NBR, and then do-something with 2.30259/3 and finaly make that an int-number.
Is that about right?
Guess the best to describe my question: i cant figure out the formula beeing used (actualy its naturaly spoken 'syntax').

Code:
	# sprintf is one topic, but what is why done with XP (1 or 0)?
	return sprintf ("%.2f%s", NBR / 10^(3*XP), U[1+XP])

Its passed NBR divided by 10 square 3 times either 0 or 1, and selecting its output string according to passed array U. (? 1+XP == XP+1 ?)
Is XP here used like 'shift' with 'getopts' (or just similar tasks)?

Code:
	# How can i check for the current line its [BP]UNT value?
	if("B" == U) { 		# This still prints output, but doesnt do the changes wanted
	## if("B" == BUNT) {	# This way it prints absolute nothing ??
		split(bitrate,B,".")
		bitrate=B[1]
	}

I've also tried if("B" in BUNT) without luck either Smilie
This last one is an attempt to remove the .00 of the bitrate colum for the values not exceeding the Byte range.

Thank you in advance for clearing up.
Have a good day!

Locale::Codes::LangFam(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangFam(3pm)

NAME
Locale::Codes::LangFam - standard codes for language extension identification SYNOPSIS
use Locale::Codes::LangFam; $lext = code2langfam('apa'); # $lext gets 'Apache languages' $code = langfam2code('Apache languages'); # $code gets 'apa' @codes = all_langfam_codes(); @names = all_langfam_names(); DESCRIPTION
The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in ISO 639-5. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5 language family codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a constant that is automatically exported by this module. For example, the two are equivalent: $lext = code2langfam('apa','alpha'); $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA); The codesets currently supported are: alpha This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages. This is the default code set. ROUTINES
code2langfam ( CODE [,CODESET] ) langfam2code ( NAME [,CODESET] ) langfam_code2code ( CODE ,CODESET ,CODESET2 ) all_langfam_codes ( [CODESET] ) all_langfam_names ( [CODESET] ) Locale::Codes::LangFam::rename_langfam ( CODE ,NEW_NAME [,CODESET] ) Locale::Codes::LangFam::add_langfam ( CODE ,NAME [,CODESET] ) Locale::Codes::LangFam::delete_langfam ( CODE [,CODESET] ) Locale::Codes::LangFam::add_langfam_alias ( NAME ,NEW_NAME ) Locale::Codes::LangFam::delete_langfam_alias ( NAME ) Locale::Codes::LangFam::rename_langfam_code ( CODE ,NEW_CODE [,CODESET] ) Locale::Codes::LangFam::add_langfam_code_alias ( CODE ,NEW_CODE [,CODESET] ) Locale::Codes::LangFam::delete_langfam_code_alias ( CODE [,CODESET] ) These routines are all documented in the Locale::Codes::API man page.
