9. EDITING PROGRAMS
The setting of an editing range start point with [CRSR] can be changed
freely until an editing range end point is set with
[CRSR] or [BTTM].
If an editing range start point is set after an editing range end point, the
editing range must be reset starting with a start point.
The setting of an editing range start point and end point remains valid until
an operation is performed to invalidate the setting.
One of the following operations invalidates a setting:
⋅ An edit operation other than address search, word search/scan, and
search for the start of a program is performed after a start point or end
point is set.
⋅ Processing is returned to operation selection after a start point or end
point is set.
In copying program and moving program, if
[EXEC] is pressed without
specifying a program number after an editing range end point is set, a
program with program number O0000 is registered as a work program.
This O0000 program has the following features:
⋅ The program can be edited in the same way as a general program.
(Do not run the program.)
⋅ If a copy or move operation is newly performed, the previous
information is deleted at execution time, and newly set information
(all or part of the program) is reregistered. (In merge operation, the
previous information is not deleted.) However, the program, when
selected for foreground operation, cannot be reregistered in the
background. (A BP/S alarm No. 140 is raised.) When the program is
reregistered, a free area is produced. Delete such a free area with the
⋅ When the program becomes unnecessary, delete the program by a
normal editing operation.
When the system is waiting for a program number to be entered,
no edit operation can be performed.
If a program number is specified by 5 or more digits, a format error is
