Multiple Area Transfer Mode (MATM)
The MATM control function determines what selected character areas the computer
can send to the host. MATM work only when SATM is reset.
Defining Selected Areas
Start selected area (SSA) and end selected area (ESA) control functions select which
characters on the current page the computer can send to the host. SSA and ESA are
8-bit C-1 control characters that can also be coded as 7-bit escape sequences. The
following conditions apply to SSA and ESA:
•
They work only when SATM is reset.
•
If the computer receives ESA before SSA, it ignores ESA.
•
If SSA is not followed by ESA on the same page, the SSA has no effect on that
page. Selected areas must always end with ESA.
•
ED, EL, or ECH control functions cannot change selected areas.
Local Edit Mode Keys
Keys with special functions in Local Edit mode are described in this table.

Find
Advances cursor to the top margin, Column 1.
Tab
Advances cursor to the next tab stop. If in protected area, it advances to the next selectable field. If tab stop
is selected, it advances to the next selectable field.
Insert here
Default mode is “insert.” Key toggles between insert and overstrike. If insert mode, all following characters
in the field are shifted right one position. If the field is full the last character is deleted.
