HP Data Entry and Forms Management System (VPLUS/V)
FIELD MENU
In case you want to assign special field characteristics, FORMSPEC
displays a Field Menu, illustrated in Figure 3-22, for each field
delimited during form design. Each menu displays up to three lines of
the form, and marks the particular field to which the menu applies. It
then displays the default field attributes of the field. The Field Menus
are presented in the order the fields appear on the form layout, from
left to right, top to bottom.
You can change the default field attributes by typing new values and
pressing ENTER. If you do not want to change the defaults, simply press
NEXT to display the next Field Menu. If you are designing simple forms,
in which all data is accepted and no special edits are performed, you can
skip all the Field Menus by pressing NEXT FORM. If you change the field
length or type, the screen length or type of the associated ARB (if any)
is updated at the same time, but the ARB length and type are not
changed.
The field attributes, all except length, can also be changed using
FORMSPEC in batch mode. See Section 7 for more information. Processing
specifications can be specified on the Field Menu. See Section 4 for a
description.

Fields
Num (Display only) A number between 1 and 256 assigned by
FORMSPEC to the field at form layout. The number is
permanently assigned to the field and is not changed
even if other field attributes or the position of the
field on the form layout changes. However, if the field
tag is changed, a new field number is assigned to the
field. The field numbers of a form can be renumbered in
screen order with the FORMSPEC batch mode command
RENUMBER, as described in Section 7.
Len (Display only) The length of the field as determined
during form layout.
Name Specify any USASCII name of up to 15 characters long; it
must start with an alphabetic character and may be
followed by any alphanumeric (A -Z, a-z, 0-9) or the
underline (_). It cannot be one of the reserved words
listed earlier in Table 3-2.
Enh Specify any combination of enhancements using up to four
characters:
H Half Bright
I Inverse video
U Underline
B Blinking
S Security

FType Specify the field type:
D Display only--cannot be modified by
user.
R Required--cannot be left blank.
O Optional--may be left blank; edit
checks and field phase processing
specifications are skipped if the field
is blank.
P Process--may be left blank, but edit
checks are performed and field phase

even if the field is blank.
Default O
DType Specify the data type:
CHAR Specifies data to be a string of any
characters.
NUM[n] Specifies data to be numeric. The
maximum number of decimal places is
indicated by the optional digit (n),
where n is a value between 0 and 9. An
optional leading sign (+ or -) is
allowed; as are commas and decimal
points if correctly placed.
DIG Specifies data to be a positive
integer. No sign, no comma, no decimal
point allowed.
IMPn Specifies data to be numeric with an
assumed decimal point. The assumed
number of decimal places is indicated
by the required digit (n), where n is a
value between 0 and 9. A sign and
commas are allowed. A decimal point is
allowed but should not be entered.
MDY Specifies data to be a date in the
order month, day, year.
DMY Specifies data to be a date in the
order day, month, year.
YMD Specifies data to be a date in the

When Native Language Support is used, the symbols
used to indicate thousands and decimals are
language-dependent. The names of months and their
abbreviations are accepted for each native language at
run-time. For more information on Native Language
Support, see Section 8.
Default CHAR
