Basic usage Even the case remaining memory of fx-5800P is reduced and new program cannot input, by using the CcLinker, it will be possible to input. Since you can save programs not normally use to the PC and whenever you need programs you can recall stored programs from the PC, therefore you can use programs without worry about remained memory. Even if a part of the program disappears due to an operation error, the stored program can be returned to fx-5800P. Since there is no undo function on the program edit screen of the fx-5800P, it cannot be recovered. Advanced usage With CcEditor (Free download from my homepage), you can create and modify fx-5800P programs on PC. CcEditor can use Greek characters and lower case letters that cannot be entered on fx-5800P main unit. Greek letters are used for messages and variables to make the program easier to read.
