enabled until bit 8 is reset to 0.
7-1 = 0 The undefined bits (7-1) must be initialized to zero.
0 = 0 Do not enable the touch feature (default).
1 Enable the touch feature.
Bits 15, 14, and 13 are used to override VSHOWFORM optimization (where
only information that has changed since the last call to VSHOWFORM is
written to the terminal screen). Bits 12 and 11 are used with VREADFIELDS
on data capture devices. Bit 10 is used when consecutive calls are made to
VSHOWFORM (no call to VREADFIELDS in between). Bit 9 is used with
terminals having local form storage capability.
Bit 8 is used to allow access to the function control keys on the HP 239X
and HP 262X terminals. For example, device control and device mode keys
can be used for local printing to an integral printer. Enabling the function
control keys using bit 8 is recommended for experienced users only. Misuse
or accidental use of certain function control keys could yield undesirable
results.
Bit 0 is used to activate touch available with terminals with the touch
feature. VREADFIELDS returns
lastkey with the field number of the
touched field (as a negative number).
printfilnum MPE file number to which a form is printed by VPRINTFORM. The formal
designator is FORMLIST.
filterrnum MPE file error number (FCHECK number) returned by VPLUS intrinsics
when an MPE file error occurs. (Refer to Appendix B for a list of the errors
that return a number to
filerrnum ).
errfilenum MPE file number of the error message file used by VERRMSG.
formstoresize Two-byte integer that indicates the number of entries allowed in the
form storage directory.
-1 No local form storage is to be performed. For the HP
2626A terminal the workspace configuration is under user
control. VPLUS does not modify terminal workspace,
window, or datacomm configuration, and either terminal
port can be used.
0 No local form storage is to be performed. For the HP
2626A terminal VPLUS reconfigures the workspaces and
windows to the terminal's default values, but only the first
terminal port can be used.
1..255 One through 255 forms can be stored locally. For the HP
2626A terminal any value greater than four defaults to
four (allowing an application to run on either the HP
2626A, HP 2394A, or HP 2624B terminals), where four
indicates that one form is the displayed form and three
forms are stored in the HP 2626A local forms storage.
VPLUS reconfigures the HP 2626A terminal workspaces
