Introduction to Programming

Chapter 10

(4) O Word Program Name

The program name, i f on the tape, must follow the program start code.

When outputting to tape, the program name can be determined by:

Program Name: If:

Manuallykeying in theprogramname -- --

Selected fromthefirstblockofthe

program

No namehasbeen manually keyedi n and the first

blockcontainsanO word,: (forEAIformat), or N word

aftertheprogramstartcode.

Selected formtheprogramdirectory No name hasbeenmanuallykeyed in and no name

exists in the firstblock oftheprogram. For theprogram

nametobe takenfromthedirectoryscreen,the

programmustbe storedonthatdirectorywith theletter

O followedbyup to 5 numericdigits. In thiscase,the

control generatesan O word blockasthe firstblockof

theprogram written to tape.

No nameisused Aprogramis stored on tapewith no programname if

none ofthe above namingconditionsaremet.

(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 end-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.

(6) Comment

Information punched between the control out code “(” and the control in

code “)” within the program section is considered a comment and is not

handled as significant information (even though it is copied to and from

control memory or tape). Any number of comments can be included in a

part program interspersed with program blocks or words.

Example 10.1

Comments in Part Programs

X1.Z1.(START MOTION);

(CALL SUBPROGRAM 1);

(12345);

Each of the above program blocks contains a comment. The control does

not regard the comment as significant information, except when it appears

in the first block of the program. In this case, the comment is displayed on

the program directory screen as part of the program name.
