11.2.7 Using the EDITING Phrase
Specifying the EDITING phrase of the ACCEPT statement enables field editing.
Table 11–3 briefly describes the keys that the EDITING phrase enables. See the
ACCEPT section of Compaq COBOL Reference Manual for a complete list of field
editing keys.
Table 11–3 Key Functions for the EDITING Phrase
Key Function Description
Left arrow Move-left Moves the cursor one space to the left. If the
cursor is at the first character position of the
field, the terminal bell rings.
Right arrow Move-right Moves the cursor one space to the right. If
the cursor is one space beyond the rightmost
character position of the field, the terminal bell
rings.
F12 (BS) Beginning-of-field Positions the cursor to the first character
position of the field.
Ctrl/E End-of-field Moves the cursor one position beyond the
rightmost character position in the field.
Ctrl/U Erase-field Erases the entire field and moves the cursor to
the first character position of the field.
F14 Switch-mode Switches the editing mode between insert and
overstrike.
Example 11–11 shows the sample code that produces the form in Figure 11–13.
