Restrictions on using the QPQCHGCF program

The following are restrictions when using the QPQCHGCF program:

• When marking fonts, the print writer must be stopped and restarted. If fonts are marked while the writer is active, unpredictable results will occur.
  • End PSF (ENDWTR), if it is active.
  • Use QPQCHGCF to mark the coded font.
  • Start PSF (STRPRTWTR).
• If a section of a font is modified, the modified section must contain all rotations that the original font contained. For example, if the coded font X0M16B is resident in the printer in rotations 0, 90,180 and 270, and section 46 is modified, then the modified section 46 must also contain rotations 0, 90, 180, and 270.
• If IBM®-supplied coded fonts are modified, you should not remove sections from the coded font as supplied. This could result in incorrect results when the modified font is referred to in a job being printed on device that does not support resident double byte raster fonts.
• PSF does not support referencing a double-byte resident raster font by its registered font ID. That is, you should not specify a double-byte font on the FONT parameter of the printer file, on the FONT DDS keyword, or with any other application that allows you to specify font with its registered font ID.
