EDIT Subcommands-DOWN, DSTRING DOWN is equivalent to the NEXT and FORWARD subcommands. When verification is on, the new current line is displayed at the
terminal; if the end of the file is reached, the message: EOF: is displayed. DSTRING Use the DSTRING subcommand to delete one or more lines beginning with
the current line, down to, but not including, the first line cont&ining a specified character string. The current line is not checked for the
character string. The format of the DSTRING subcommand is: r I DString L- I I[ string[ I] )
.----------_________________________________________________ -J / (diagonal) signifies any unique delimiting character that does not
appear in the string.
string specifies the group of characters for which a search is to
be made. If string is not specified, only the current line
is deleted.
The zone set by the ZONE subcommand or the default zone setting is
checked for the presence of the character string. A character string
with a length greater than the current zone setting causes the error
message ZONE ERROR. If the character string is not found by the end of the file, no
deletions occur, the current line pointer is unchanged, and the message:
is displayed.
If verification is on when the DSTRING subcommand is issued at a display
terminal in display mode, the screen is changed to reflect the deletions
from the file.
