The only way I know is to go to the end of the program, then hit "2nd","STO>" (this will select RCL). the hit the prgm button, scroll to EXEC, then select the program from which the code is from, The hit enter. This will paste the whole code program into your current program. Then you have to delete the unwanted code. You cant paste the same program into the same program (eg. working in TEST, you cant coopy the code from program TEST). however, you could create a seperate program, copy in the whole code from the wanted program (eg. TEST as i mentioned before) then go back to your wanted program and paste in the code from the new program you just created. And again, delete away the unwanted code. unless of course you want to copy in the Entire program code. Thats all I got.
