OS_Bout, Write null-terminated string block at (B)HL to standard output

Register parameters

RST 20H, DEFW $90

IN:
  BHL = extended pointer to string to be written (not crossing segments)
  B = 0, then local address space pointer in caller bank binding

OUT:
   Fc = 0 always (error handler is never provoked)
   HL points at byte after null-terminator

Registers changed after return:
   A.BCDE../IXIY same
  .F....HL/.... different

Notes

Available in OZ V4.2 and newer.

Fast block string output. It is the internal call of GN_Soe. Use this one for faster processing (lower OZ overhead).
