Hi.

Make you feel at home:
Code:
#!/usr/bin/env rexx

/*
# @(#) s1       Demonstrate Linux rexx.
*/

subject = 'We are looking for an item in a line.'

If WORDPOS('item', subject) > 0 Then
  SAY 'Found it.'
Else
  SAY ' Cannot see item.'

exit 0

Producing:
Code:
% ./s1
Found it.

Make me feel at home:
Code:
#!/bin/bash -

# @(#) s1       Demonstrate rexx function emulation.

debug="echo"
debug=":"

wordpos() {
  local phrase="$1" string="$2"
  $debug " wordpos, looking for $phrase in $string"
  if [[ $string == *$phrase* ]]
  then
    return 0
  else
    return 1
  fi
}

if wordpos item "Jack and Jill"
then
  echo " Found it (unexpected!)."
fi

if wordpos item "Now here is an item embedded."
then
  echo " Found it (expected)."
fi

exit 0

Producing:
Code:
% ./s2
 Found it (expected).

The key to s2 is not the function, of course, it is the syntax of and in the if statement. The page at http://www.tldp.org/LDP/abs/html/index.html is long, but valuable... cheers, drl

locale::codes::langext

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

NAME

       Locale::Codes::LangExt - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangExt;

	  $lext = code2langext('acm');		       # $lext gets 'Mesopotamian Arabic'
	  $code = langext2code('Mesopotamian Arabic'); # $code gets 'acm'

	  @codes   = all_langext_codes();
	  @names   = all_langext_names();

DESCRIPTION

       The "Locale::Codes::LangExt" module provides access to standard codes used for identifying language extensions, such as those as defined in
       the IANA language registry.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language
       registry codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language extensions. 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 = code2langext('acm','alpha');
	  $lext = code2langext('acm',LOCALE_LANGEXT_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from the IANA language registry, such as 'acm' for Mesopotamian Arabic.

	   This is the default code set.

ROUTINES

       code2langext ( CODE [,CODESET] )
       langext2code ( NAME [,CODESET] )
       langext_code2code ( CODE ,CODESET ,CODESET2 )
       all_langext_codes ( [CODESET] )
       all_langext_names ( [CODESET] )
       Locale::Codes::LangExt::rename_langext  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangExt::add_langext  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangExt::delete_langext  ( CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangExt::delete_langext_alias  ( NAME )
       Locale::Codes::LangExt::rename_langext_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::delete_langext_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
