IBM 3270 Differences and Limitations
terminals
• Local field edits that occur in the terminal firmware,
such as edits for numeric fields
Screen Enhancements
Several HP terminal display enhancements are unavailable on the IBM 3270. You do not
have to alter any enhancements specified in an existing forms file for IBM 3270 usage,
however.
Table K-3 summarizes the mapping of HP display enhancements to IBM 3270 display
stations. The codes provided for some of the HP display enhancements correspond to the
value specified in FORMSPEC for the display enhancements of fields, errors, and the
window line. Note that the half-bright enhancement (code=H) overrides all other
enhancements except for security.
Function Key Labels
VPLUS simulates function key labels by "reserving" the last two lines of the screen. This
reduces the available screen area to 22 lines.
Function key labels for IBM 3270 display stations appear similar to those for HP
terminals. The label text appears on an IBM 3270 display station as intensified display on
a blank background. The default labels on HP terminals and IBM 3270 display stations
are identical, and cannot be configured by users.
