/*
**  Purpose:
**      Multi Edit Dialog procedure for templates with multiple edit controls.
**  Control IDs:
**      The Edit controls must have IDs of IDC_EDIT1 to IDC_EDIT10.
**      Pushbuttons recognized are IDC_O, IDC_C, IDC_M, IDC_H, IDC_X, and IDC_B.
**  Initialization:
**      The symbol $(EditTextIn) is used to set the initial text in the Edit
**      controls.  The symbol $(EditTextLim) is used to set the limit of the
**      text in the edit fields.
**  Termination:
**      The strings in the Edit controls are stored in the symbol $(EditTextOut)
**      The id of the Pushbutton (eg IDC_C) which caused termination is
**      converted to a string and stored in the symbol $(ButtonPressed).
