How many digits will you have (the above is for 3 digits)? And I suppose you want to check only the last digit?

--ahamed
Digits are inconsistent as well. Can be 3, can be 10. Is the solution above going to work?

it should work for when only numerals appear after the Code/string construct. I have not tested this.

What does the "+" sign do? Is it like the "*" in ls ?

wstring(3C)						   Standard C Library Functions 					       wstring(3C)

NAME
wstring, wscasecmp, wsncasecmp, wsdup, wscol - Process Code string operations SYNOPSIS
#include <widec.h> int wscasecmp(const wchar_t *s1, const wchar_t *s2); int wsncasecmp(const wchar_t *s1, const wchar_t *s2, int n); wchar_t *wsdup(const wchar_t *s); int wscol(const wchar_t *s); DESCRIPTION
These functions operate on Process Code strings terminated by wchar_t null characters. During appending or copying, these routines do not check for an overflow condition of the receiving string. In the following, s, s1, and s2 point to Process Code strings terminated by a wchar_t null. wscasecmp(), wsncasecmp() The wscasecmp() function compares its arguments, ignoring case, and returns an integer greater than, equal to, or less than 0, depending upon whether s1 is lexicographically greater than, equal to, or less than s2. It makes the same comparison but compares at most n Process Code characters. The four Extended Unix Code (EUC) codesets are ordered from lowest to highest as 0, 2, 3, 1 when characters from different codesets are compared. wsdup() The wsdup() function returns a pointer to a new Process Code string, which is a duplicate of the string pointed to by s. The space for the new string is obtained using malloc(3C). If the new string cannot be created, a null pointer is returned. wscol() The wscol() function returns the screen display width (in columns) of the Process Code string s. ATTRIBUTES
