Adds a field with the specified properties
to the temp-table. Additional properties can be manipulated by creating
a buffer-field object for this field.
This method cannot be
called after TEMP-TABLE-PREPARE( ) has been called unless
CLEAR( ) is called first.
Return type: LOGICAL

-
field-name-exp
- A character expression that evaluates to the name of the field
to be created in the temp-table.
-
datatype-exp
- A character expression that evaluates to the data type of the
specified field.
-
extent-exp
- An integer expression specifying the extent of an array. If extent-exp is
0, 1 or the Unknown value (?), it is ignored.
-
format-exp
- A character expression that evaluates to the data format for
the defined data type. If format-exp is "" or
the Unknown value (?), it is ignored and the default format
of the specified data type is used.
-
initial-exp
- An expression that evaluates to the initial value of the defined
field. initial-exp can be any compatible data
type, but is usually character. If initial-exp is
not entered, the default for the data type is used.
-
label-exp
- An optional character expression that evaluates to the label
of the defined field. If you do not specify a value, or you pass
the Unknown value (?), label-exp defaults
to the value of the field-name-exp parameter.
-
column-label-exp
- An optional character expression that evaluates to the label
of the column associated with the defined field. If you do not specify
a value, or you pass the Unknown value (?), column-label-exp defaults
to the value of the label-exp parameter (or the field-name-exp parameter,
if the label-exp parameter is not specified).
The
following example fragment adds a new character field called "abfield" which
is initialized to "abc" to a temp-table:
tth:ADD-NEW-FIELD("abfield","char",0,,"abc").

Note: There is a limit to the number
of fields that can be accommodated in a temp-table object. The limit
depends on how large the field information (initial value, validate
information, help messages, etc.) is, but you should plan on a limit
of approximately 1,000 fields.
