When a program starts all variables are set to 0 or "" for strings. The simplest way to save them is with VAR SAVE before the program ends then on restarting use VAR RESTORE to retrieve them. The manual has more details. The other method is to save them to a file. |

Hi Gerad, Whenever you feel the value of a variable should be "saved" in your program , do a "VAR SAVE variable" (i.e. VAR SAVE a$). In the beginning of your program you add the line "VAR RESTORE". You do not need to specify a variable, it restores everything that has been saved with VAR SAVE so far. Be aware though. When you "LOAD" a different program, the VAR SAVE memory is cleared. That is to prevent that values of one program polute another program at startup. Regards, Volhout PicomiteVGA PETSCII ROBOTS |
