#LINEDEL Built-In Function

Use #LINEDEL to delete lines from a variable level, starting at a specified line.

variable-level

is an existing variable level from which lines are to be deleted. It must not be in a

shared segment, and must not be a DIRECTORY, a STRUCT, or a STRUCT item.

line-addr-1

is an integer or a variable level that contains an integer. line-addr-1 specifies

the line number at which line deletion is to begin. The line address must be in the

range from 1 to max-int, inclusive.

line-count

is an integer or a variable level that contains an integer. line-count specifies the

number of lines to be deleted. The line count must be in the range from 0 to max-

int, inclusive.

line-addr-2

is an integer or a variable level that contains an integer. line-addr-2 specifies

the line number at which line deletion is to end. The line address must be in the

range from 0 to max-int, inclusive.

Result

#LINEDEL returns nothing.

Considerations

•

If you use TO, the line specified by line-addr-2 is included in the deletion: That

is, “x TO y” is equivalent to “x FOR (y-x)+1.”

•

If you use TO and line-addr-1 is greater than line-addr-2, no deletion

occurs.

•

If you omit both FOR and TO, TACL deletes the line specified by line-addr-1.

Examples

Any part of the specified deletion that lies beyond the end of the variable level is

ignored.
