We try to ensure the backwards compatibility of IDL save files containing common blocks and/or local variables. You should not expect save files containing system variables or compiled IDL routines to be compatible with future releases of IDL. For this reason, saving system variables is not recommended. If the save file only contains IDL routines, then you will need to recompile those routines, using the current version of IDL, and then recreate the save file using the ROUTINES keyword to the SAVE procedure. For additional information, please refer to the documentation for the SAVE and RESTORE procedures in the online help. Please login or register to post comments.
