EDIT Use the EDIT command when you want to change a statement that has been typed into memory without re-typing the entire line. Just type EDIT and the line number and press the ENTER key. The statement will appear on the display. Use the LEFT-ARROW and RIGHT-ARROW keys to move the cursor. Use the DEL key to remove an unwanted character, or simply type in new characters. Example: 10 INPUT B EDIT 10 press ENTER press ENTER 10 INPUT B_ Then use Left-Arrow key to move the cursor back under"B". 10 INPUT B Then type in "C". 10 INPUT C_ You can type in line-numbered BASIC statements in any order. PRECOMPUTER POWER PAD™ PLUS will sort them out for you and LIST them or RUN them starting with the lowest numbered one. It is a good idea to number your lines in increments of 10 (10, 20, 30...) or 100 (100, 200, 300...). This way you have room to add more statements if you decide to change your program in the future. You can insert an entirely new line in a program by using a line number that doesn't exist between two existing ones. You can delete an existing line-numbered statement by merely typing the line number and pressing the ENTER key. Of course, you can change an existing line by merely re-typing the entire line. END Line # END The END statement is used as the last command in a program. It stops the program. Examples: 160 END 999 END 48
