In posting<1370@ism780c.UUCP>, Tim Smith asks about a switch with common
code for some cases. I have seen two solutions.

1) put the common code in a subroutine
        switch(thing) {
        case A: A-code; break;
        case B: B-code; BCD-common-code(); break;
        case C: C-code; BCD-common-code(); break;
        case D: D-code; BCD-common-code(); break;
        case E: E-code; break;
        }

2) use the much abused goto statment
        switch(thing) {

        case A: A-code; break;

        case B: B-code; goto BCD_common;

        case C: C-code; goto BCD_common;

        case D: D-code;

    BCD_common: BCD-common-code;
                break;

        case E: E-code; break;
        }


Hope one of these helps you.
