The tape end code, indicating the end of a tape, is designated with either:
Code: Description:

ER EIA format
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 symbolthat means somethingspecific tothe
control. For example, 1 G ; are charactersthat the controlrecognizes
as meaningfulinformation.
address a letter that definesthe instructionfor the control. Examples of addresses
are: G, X, Z, F.
word an address followedby anumeric value. Examples of wordsare: G01,
X10.5, F.1., M2. Each wordrequires a specific format for its numericpart.
These formats are givenon page10-20 .
code industry standards for manyof the G- and M-codesused here. For that
reason, they areoften referredto asG- or M- “codes.”
parameter a number of fixedcycles that areinitiated bya specificG-code. Other
words appearingin thoseG-code blocksare referred to as “parameters”
because their values are relevant only to that G-code. For example, a
Z-word generally refers toa Zaxis move, but whenit appears ina block
with a G83 peck drilling cycle, itsvalue refers to thedepth of the hole to
be drilled. In that case, it isa “parameter”of the G83fixed cycle.
