The line will scroll within a window determined by the screen width of the currently defined CRT device. Up to 127 characters may be entered. The editor is always in "insert" mode. Only the single previous command may be recalled, and it will OVERLAY the current line from the cursor position forward. For instance, if you enter "DIR *.BAK" and then enter "ERA ^R", the result will be "ERA *.BAK". The previous command is stored in a shell variable named "LASTCMD"; this variable may be accessed just as other shell variables are.
