As i see it, not really understanding awk yet, but you're comparing a STRING (a) with an INTEGER (k).
Anyhow, so you pass a list of variables, and when it matches a certain string, you want to call that function?
Must it be awk, because bash works just fine
Code:
#!/bin/bash
my_func_local() {
echo "In func: my_func_local $1"
}
for ARG in "${@}";do
[[ $ARG = a ]] && \
my_func_local $ARG || \
echo $ARG
done
Code:
sh script.sh a b c d
In func: my_func_local a
b
c
d

I'm an experienced awk user, but this one has me stumped. I have an awk script which is called from a UNIX command line as you'd expect:

xml::grove::subst
XML::Grove::Subst(3pm) User Contributed Perl Documentation XML::Grove::Subst(3pm)NAME
XML::Grove::Subst - substitute values into a template
SYNOPSIS
use XML::Grove::Subst;
# Using subst method on XML::Grove::Document or XML::Grove::Element:
$new_grove = $source_grove->subst( ARGS );
$new_grove = $source_grove->subst_hash( ARG );
# Using an XML::Grove::Subst instance:
$subster = XML::Grove::Subst->new();
$new_grove = $subster->subst( $source_grove, ARGS );
$new_grove = $subster->subst_hash( $source_grove, ARG );
DESCRIPTION
"XML::Grove::Subst" implements XML templates. "XML::Grove::Subst" traverses through a source grove replacing all elements with names
`"SUB:XXX"' or `"SUB:key"' with their corresponding values from ARGS (a list) or ARG (a hash), repsectively.
METHODS
$grove_obj->subst( ARGS ) =item $subster->subst( $grove_obj, ARGS )
Search for `"SUB:XXX"' elements, where XXX is an array index, and replace the element with the value from ARGS, a list of values. The
return value is a new grove with the substitutions applied.
$grove_obj->subst_hash( ARG ) =item $subster->subst_hash( $grove_obj, ARG )
Search for `"SUB:key"' elements and replace the element with the value from ARG, a hash of values. The hash key is taken from the
`"key"' attribute of the `"SUB:key"' element, for example, `"<SUB:key key='foo'>"'. The return value is a new grove with the
substitutions applied.
EXAMPLE
The following template, in a file `"template.xml"', could be used for a simple parts database conversion to HTML:
<html>
<head>
<title><SUB:key key='Name'></title>
</head>
<body>
<h1><SUB:key key='Name'></title>
<p>Information for part number <SUB:key key='Number'>:</p>
<SUB:key key='Description'>
</body>
</html>
To use this template you would first parse it and convert it to a grove, and then use `"subst_hash()"' every time you needed a new page:
use XML::Parser::PerlSAX;
use XML::Grove;
use XML::Grove::Builder;
use XML::Grove::Subst;
use XML::Grove::PerlSAX;
use XML::Handler::XMLWriter;
# Load the template
$b = XML::Grove::Builder->new();
$p = XML::Parser::PerlSAX->new( Handler = $b );
$source_grove = $p->parse( Source => { SystemId => 'template.xml' } );
# Apply the substitutions
$new_grove = $source_grove->subst_hash( { Name => 'Acme DCX-2000 Filter',
Number => 'N4728',
Description => 'The Best' } );
# Write the new grove to standard output
$w = XML::Handler::XMLWriter->new();
$wp = XML::Grove::PerlSAX->new( Handler => $w );
$wp->parse( Source => { Grove => $new_grove } );
