In case you want to assign special field characteristics,
FORMSPEC displays a Field Menu, illustrated in Figure 3-21 “Field Menu”,
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 Figure 3-2 “Main Menu” - Enh
Specify any combination of enhancements using up
to four characters: - 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 processing specifications are executed
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 order year, month,
day.
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. - Initial Value
Specify data to be displayed in the field when the
form is initially displayed.
