Introducing Workstation Conﬁgurator

What Characteristics are Modiﬁable?

The second type is the same as the Additional EOR speciﬁed through

the FCONTROL(25) intrinsic. The character is included in both the data

and the actual count of the number of bytes returned. The read is

returned with a special status (a returned condition code of CCL on the

read and a ﬁle system error number of FSERR 31), indicating that the

read was terminated by the additional EOR character. The terminal

cursor is not affected.

Subsystem Break

The subsystem break function enables you to interrupt the execution of

a local program or subsystem command. The subsystem break

character is invoked by pressing

[CTRL]-[Y]. Using Workstation

Conﬁgurator, one subsystem break character can be speciﬁed.

Echo

Echo allows terminal input to be echoed back to the terminal screen by

the computer as it is received. With Workstation Conﬁgurator, the

initial setting for echo (either on or off) can be speciﬁed. Whenever the

terminal type is set, the initial setting for echo will take effect.

NOTE Applications exist that set echo before the terminal type is selected. For

applications to function correctly, the program needs to select the

terminal type ﬁrst, and then set echo as desired (if it is different than

the default

Form Feed

The form feed character is usually contained in the carriage control

sent to the hard copy printer. Some hard copy printer will not accept the

form feed character. Workstation Conﬁgurator can be used to replace

the form feed character with a character that the hard copy printer will

accept. In most instances, the form feed character is replaced with the

line feed character.

Subsystem Response to Backspace

When echo is enabled, a backspace is echoed to the terminal screen

which might cause some action to the data on the screen. An additional

response might be required from the system for better cursor

positioning. The default for backspace causes the cursor to backup one

space, but it does not erase the character. Workstation Conﬁgurator can

be used to specify that the character should be erased.

Typeahead

Typeahead allows the terminal user to continuously enter data without

having to wait for the system to process the data and return the

MPE/iX prompt (:). Typeahead echo mode determines whether input
