X 8.1.5 DELETE Statement
X The DELETE statement is an extended source library statement. It removes
X COBOL statements from the source program included by a BASIS statement.
X ___ Format _____________________________________________________________

X | >>__ _________________ __DELETE__sequence-number-field______________>< |
X | |_sequence-number_| |
X Can optionally appear in columns 1 through 6, followed by a space.
X The content of this field is ignored.
X Can appear anywhere within columns 1 through 72. It must be followed
X by a space and the sequence-number-field. There must be no other text
X in the statement.
X Each number must be equal to a sequence-number in the BASIS source
X program. This sequence-number is the 6-digit number the programmer
X assigns in columns 1 through 6 of the COBOL coding form. The numbers
X referenced in the sequence-number-fields of any INSERT or DELETE
X statements must always be specified in ascending numeric order.
X The sequence-number-field must be any one of the following:
- X A single number
- X A series of single numbers
- X A range of numbers (indicated by separating the two bounding
X numbers of the range by a hyphen)
- X A series of ranges of numbers
- X Any combination of one or more single numbers and one or more
X ranges of numbers
X Each entry in the sequence-number-field must be separated from the
X preceding entry by a comma followed by a space. For example:
X 000250 DELETE 000010-000050, 000400, 000450
X Source program statements can follow a DELETE statement. These source
X program statements are then inserted into the BASIS source program before
X the statement following the last statement deleted (that is, in the
X example above, before the next statement following deleted statement
X If a DELETE statement is specified, beginning in column 12 or higher, and
X a valid sequence-number-field does not follow the key word DELETE, the
X compiler assumes that this DELETE statement is the COBOL DELETE statement.
X New source program statements following the DELETE statement can include
X DBCS or EUC data items.
X Note: If INSERT or DELETE statements are used to modify the COBOL source
X program provided by a BASIS statement, the sequence field of the COBOL
X source program must contain numeric sequence-numbers in ascending order.
X The source file remains unchanged. Any INSERT or DELETE statements
X referring to these sequence-numbers must occur in ascending order.
