- array is the array of records that will be filled by the
INPUT ARRAY
statement. - help-number is an integer that allows you to associate a help message number with the instruction.
- field-name is the identifier of a field of the current form.
- table-name is the identifier of a database table of the current form.
- screen-record is the identifier of a screen record of the current form.
- screen-array is the screen array that will be used in the form.
- action-name identifies an action that can be executed by the user.
- seconds is an integer literal or variable that defines a number of seconds.
- key-name is a hot-key identifier (like
F11
orControl-z
). - statement is any instruction supported by the language.
- row-count defines the initial number of rows for a static array.
- max-row-count is the maximum number of rows that can be created.
- boolean is a boolean expression that evaluates to
TRUE
orFALSE
. - action-attributes are dialog-specific action attributes.
