//=== CenterStr ================================================
// Return the centered string. The input string is normally
// fixed length and RPG will promote it to varying on the
// call. A varying string is returned which RPG will reset
// to fixed if needed.
// It will also execute with a varying string input but the
// result may not be what you expect.
//
// Conceptual call:
//=================
// H BndDir('UTIL_BND')
// /include Demo,Srv_Str_P
// d Head S 20A inz('Inquiry')
// Head = CenterStr(Head);
// Notes:
// CenterStr is small, but it is convenient.
// Could add left and right justify, but...
// Left justify is simple in RPG:
// str = %trim(str);
// Right justify is also simple:
// evalr str = %trim(str);
