(3) Program Start Code
The first end-of-block code (EOB code) after the leader section indicates
the beginning of the part program. The EOB c ode is designated with:
line feed (LF) ---- ASCII format
carriage return (CR) ---- EIA format
Important: When performing an EOB search, the search is executed from
the beginning of the part program, NOT from the point of display.
(4) O--word Program Name
The program name, if on the tape, must follow the program start code.
When outputting to tape the program name can be determined by:
Program Name: If:
Manually Keying intheprogramname -- --
Selected fromthe firstblock of theprogram No name hasbeen manually keyed inand the firstblock
contains anO--word,:(forEIAformat),orN--wordafterthe
programstartcode.
Selected formthe programdirectory No namehas been manually keyedinand noname exists
inthefirstblockoftheprogram. For the programname to
be takenfrom the directoryscreentheprogrammustbe
stored on thatdirectorywith the letterOfollowed byup to 5
numeric digits. Inthis casethe controlwillgenerate an
O-- wordblock as the firstblock ofthe programwritten to
tape.
Noname is used Aprogramwill bestored on tapewith noprogram name if
none of theabove naming conditionsaremet.
(5) Part Program Section
A part program is made of blocks of information. Individual blocks
contain words that the control can interpret. Individual words are made up
of an address with a numeric value. For details on words and addresses,
see the remaining sections of this chapter.
This section should include a program name, program blocks, comments,
and e nd-of-program. Each block in the part program is separated by an
EOB code. The control displays a semicolon “;”to indicate the presence
of an EOB code.
