Documenting

our Ladder Program

You have the option of documenting your program before or after it is entered. If

program to someone else who has to read, modify, or maintain the program.

Deleting Comments and Symbols

Deleting a comment, line, or word places it in the corresponding buffer. If you

choose to insert the deleted item in this or another comment, select the appropriate

delete another comment, line, word, or exit the document function.
