ALL: Specifies that all selected lines are deleted. The DELETE command, unlike FIND, CHANGE, and EXCLUDE, does not use NEXT, FIRST, PREV, or LAST. ALL is required to emphasize that NEXT is not the default.
X: Restricts the lines deleted to those that are excluded.
NX: Restricts the lines deleted to those that are not excluded.
labela, labelb: Labels identifying the start and end of the group of lines to be deleted. To delete one line, enter one label.
linenum1: Relative line number identifying a line, or the start of a group of lines, to be deleted.
linenum2: Relative line number identifying the end of a group of lines to be deleted.

Description

DELETE can specify a single line or a range of lines. It can limit the lines to be deleted to all excluded or non-excluded lines in the data, or to all excluded or non-excluded lines within a line pointer range.

Return codes

0: Normal (lines deleted successfully)
4: No lines deleted
8: No standard records exist
12: Invalid line number
20: Severe error
