END: OPCODE

If the file already exists, you go directly

L 1! 0

into the first line of the program. If you are
creating a new file, the screen shown in this
example is displayed. An END statement is
automatically supplied as the last instruction.
Key in the first line of your program, entering
either the opcode or mnemonic for the
instruction. For this example, let's say the
mnemonic is JNK.

JNK

JNK: PARAMETER

You are asked to enter a parameter if one is

L 1!

required for the instruction you entered. In
this example, the parameter required is the
jump location (line number).

Parameter

END: OPCODE

Enter the second line of the program, and so

L 2! 0

on until you have entered all the instructions.

Guide to Editing Program Files
❏ To insert a line in a program, press <Ð>, then enter the appropriate

opcode in place of the END statement.

❏ If you insert or delete a line, remember to change line number references in the Polycode

parameter fields to match the renumbered program. You can use the NOP command as a
place holder in a list of Polycode instructions if you need to delete an instruction so you do
not have to change all the line number references in the subsequent lines in the program.

❏ It is much easier to modify a Polycode program using PolyTools on the computer and

send the new version to the FieldBook for testing. The PolyTools mode “PolyTran” accepts
symbolic labels, then translates them to actual line numbers during compilation.

❏ When you are satisfied the program file is correct, press to compile the program.
