AHELP for CIAO 4.6 ChIPS v1

delete_line

Context: lines

Synopsis

Delete the specified line.

Syntax

delete_line()
delete_line(id)

Description

The function arguments.

Argument Description
id A ChipsId structure identifying the item, or a string containing the name of the object.

If no argument is given then the current line is deleted, otherwise the argument determines what to delete.

Example 1

chips> add_line(0, 0, 1, 1)
chips> delete_line()

Create a line, then delete it.

Example 2

chips> id = ChipsId()
chips> add_line(.1, .3, .9, .3, "id=flat")
chips> add_line(.3, .8, .8, .2, "id=slope")
chips> id.line = "flat"
chips> delete_line(id)

Two lines are created; the second line is current after it is created. The id.line command sets the line value of the ChipsId structure to the first line. That line is then deleted.

Example 3

chips> add_line(0, 0, 1, 1)
chips> add_line(.1, .3, .9, .3)
chips> delete_line("all")

Two lines are created, then the delete_line command deletes them both.
