The operator can recall a form from the form buffer into the compose buffer, where it is visible if 
the compose buffer has the focus. 

The host can use certain expanded functions to recall a form from the DOS terminal’s form buffer. 

The compose buffer is a conceptual buffer that holds form messages and user input. 

The host application deletes forms from the form buffer in the DOS terminal. 

The host application can send a form message with any character other than the right square 
bracket ] or the number symbol # in the third text position to delete a form from the form buffer. 

The following message is an example of one that deletes a form from the form buffer: 

 

 

 

 

occupies the position of the third 

character in the form, which deletes 
the form from the terminal’s form 
buffer.

Once the host transmits a form or the DOS terminal accesses a stored form, a copy of the form 
remains in the form buffer. The form can be copied from the form buffer to the compose buffer 
where the operator can enter data. This is known as a form recall.  

The operator may at any time recall a form from the form buffer by pressing the [ALT] [1] key 
sequence. If there is currently no form in the form buffer, this action will have no effect. 

The host application can recall any form in the form buffer with Expanded Function G, g, P, p.
