Abstract

The article at pages 3833 to 3836 describes the use of an action table environment on a data-entry terminal which permits the host application to describe activities which are to be performed when the operator depresses a key which would cause the cursor to leave a 'primed' field. One such action is to write a message at some buffer address.

Field Attribute Modification on Data-Entry Display Terminal

The article at pages 3833 to 3836 describes the use of an action table environment on a data-entry terminal which permits the host application to describe activities which are to be performed when the operator depresses a key which would cause the cursor to leave a 'primed' field. One such action is to write a message at some buffer address. If this message includes the 'Modify Field' order, the host application is able to construct a display panel such that as any field is completed by the operator, then a) another field can be specified as 'mandatory enter', thus requiring the operator to submit data in the dependent

field, b) this field can be changed to protected, thus

preventing the operator from altering the data

of this field, c) this field (or another field) can be made display/non

display/intensified/normal. This new function in the device provides the host application with a variety of capabilities, hitherto unachievable without an interaction with the host.
