Response to reggie
Reggie,
Sorry, but that is not the problem. The problem is that the regular expression is not seeing the forward slash (/).
For example, the following string should evaluate to 'good data'.
$variable = 'RWD/FWD';
if ( $variable =~ /^[a-zA-Z0-9\/]*$/ )
#allow alphanumeric and fwd slash only
{
$returnValue = 'good data';
}
else
{
$returnValue = 'Bad Data';
}

fnmatch
FNMATCH(3) Linux Programmer's Manual FNMATCH(3)
NAME
fnmatch - match filename or pathname
SYNOPSIS
#include <fnmatch.h>
int fnmatch(const char *pattern, const char *string, int flags);
DESCRIPTION
The fnmatch() function checks whether the string argument matches the pattern argument, which is a shell wildcard pattern.
The flags argument modifies the behaviour; it is the bitwise OR of zero or more of the following flags:
FNM_NOESCAPE
If this flag is set, treat backslash as an ordinary character, instead of an escape character.
FNM_PATHNAME
If this flag is set, match a slash in string only with a slash in pattern and not, for example, with a [] - sequence containing a
slash.
FNM_PERIOD
If this flag is set, a leading period in string has to be matched exactly by a period in pattern. A period is considered to be
leading if it is the first character in string, or if both FNM_PATHNAME is set and the period immediately follows a slash.
FNM_FILE_NAME
This is a GNU synonym for FNM_PATHNAME.
FNM_LEADING_DIR
If this flag (a GNU extension) is set, the pattern is considered to be matched if it matches an initial segment of string which is
followed by a slash. This flag is mainly for the internal use of glibc and is only implemented in certain cases.
FNM_CASEFOLD
If this flag (a GNU extension) is set, the pattern is matched case-insensitively.
RETURN VALUE
Zero if string matches pattern, FNM_NOMATCH if there is no match or another non-zero value if there is an error.
CONFORMING TO
ISO/IEC 9945-2: 1993 (POSIX.2). The FNM_FILE_NAME, FNM_LEADING_DIR, and FNM_CASEFOLD flags are GNU extensions.
