Description

The length of the output page buffer for full screen connections and back pages

LOUTPB must be large enough to hold the new screen size if the MODEL parameter is used to take advantage of the alternate screen sizes within the 3270 terminal family. The recommended value for LOUTPB is 1.5 times the minimum value.

LOUTPB must be greater than or equal to the product of OUTMRL and OUTLPP for non-full-screen connections that have an NBKPG parameter greater than 0.

The range of values for LOUTPB is 0 to 32767. If NBKPG is greater than 0, the largest allowable value for LOUTPB is PAGESZ minus 40.

MODEL 6

As of Model 204 version 7.7 (and 7.5 or 7.6 with maintenance applied), a large LOUTPB value for MODEL 6 geometries is allowed, even if screen back-paging has been enabled. In previous releases, during initialization, if back-paging was enabled for the IODEV, LOUTPB was automatically reset to the limit that supported back-paging. Back-paging is now disabled for any terminal with a MODEL 6 screen geometry that requires more than 6142 bytes.
