awk saving field of first file into array

Hello guys, I just start trying out AWK and encounter a problem, I try to think a bit but seems my way is incorrect.
I have two input file, with the first file has only one field, the second file has 3 fields, I suppose to do stuffs to them by writing an awk program, kinda sort them out. Since I am not suppose to know how many records the first file has, I cant just use a for loop. I would like to save each record of the first file into an array so I can begin to compare to second file and sort thing out. But I am not sure how, can you guys give me an idea?

Sorry for my english, I am not native to the language.
I did a silly attemp by doing:
Code:
{ while (NR == FNR)}

but it obvious give me an infinite loop, what I want to know is how can I tell that I can stop assign fields to array when it begins to read the second file?

So what I desire is:
File1
Code:
CoCo
Hiel
Euda
SJHF
Euda
CoCo

File2:
Code:
CoCo   $39.4   paid
CoCo   $34   due
Euda   45   paid

If there is no $, that line is invalid, also the two digits after decimal points.
first field can appear several times.
If first field in file 1 not appear in file 2, print out balance 0, same thing with invalid line.
Desired output:
Code:
CoCo balance:$5.4
Hiel balance:$0.00

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
