Hello, All!

 I have to write regexp to match all of that strings: `HR-16', `HR-32',
`ZR-16', `ZR-32'. I try this:

==================  Begin of rege.cc  =================
#include <iostream>
#include <stdio.h>
#include <_String.h>

int main(void)
{
    Regex rx ("[HZ]R-(16|32)");  // <-- there trouble ;-(
    String s;
    char str[128];

    cout << "Input string: ";
    cin.getline(str, 127);
    s = str;

    if( s.contains(rx) )
        cout << "Matched!" << endl;
    else
        cout << "Don't match ;-(" << endl;

     cout << s;

    return 0;
}

/*
 * Local variables:
 * compile-command: "gpp -O2 -o rege -s rege.cc -lgpp"
 * End:
 */
===================  End of rege.cc  ==================

If I write regexp "[ZH]R-(16)" that don't match string ZR-16, but if I write
"[ZH]R-\\(16\\)" that matched ZR-16 & HR-16, but I need ZR-16 & ZR-32! And if I
write "[ZH]R-\\(16|32\\)" that don't match nor ZR-16 nor ZR-32 and nor HR-16
etc. I have gcc 2.95.  Please help me, or sent me via e-mail documentation on
regexps from djgpp with _examples_.

Thank You for Your answer.
