(8) Tape End (Rewind, Stop Code)
The tape end code, indicating the end of a tape, is designated with either:
Code: Description:

Each individual machining operation performed by the control is
determined by the control’s interpretation of a group of words or codes
(commands) called a “block.” Individual blocks in a part program define
each machining process. Part programs consist of a number of blocks that
define a complete operation of a part.
Part program blocks are made up of:
Component of
program block:
Description:
character a number, a letter, or a symbol that means something specific to the
control. For example, 1 G ; are characters that the control recognizes
as meaningful information.
address a letter that defines the instruction for the control. Examples of addresses
are: G, X, Z, F.
word an address followed by a numeric value. Examples of words are: G01,
X10.5, F.1., M2. Each word requires a specific format for its numeric part.
These formats are given on page 10-20 .
code industry standards for many of the G- and M-codes used here. For that
reason, they are often referred to as G- or M- “codes.”
parameter a number of fixed cycles that are initiated by a specific G-code. Other
words appearing in those G-code blocks are referred to as “parameters”
because their values are relevant only to that G-code. For example, a
Z-word generally refers to a Z axis move, but when it appears in a block
with a G83 peck drilling cycle, its value refers to the depth of the hole to
be drilled. In that case, it is a “parameter”of the G83 fixed cycle.
