4-34 PostScript Note: Some printer models released in the year 2000 or later designated as Energy Star printers cannot have Power Saver disabled. This operator is equivalent to executing the following PostScript emulation sequence: currentpagedevice /PowerSave get Error: stackoverflow ramsize - ramsize integer queries the current setting of the RamSize system parameter. An integer is returned on the stack showing total RAM in bytes. This operator is equivalent to executing the following PostScript emulation sequence: currentsystemparams /RamSize get Error: stackoverflow realformat - realformat boolean returns a boolean with the same value as the RealFormat system parameter. It indicates the printer microprocessor native real number representation. A query determines if the printer real number representation matches the application real number representation and compensates if necessary. Error: stackoverflow renamefile oldfilename newfilename renamefile renames the oldfilename to the newfilename. This operator is in systemdict. Errors: invalidfileaccess, ioerror, stackunderflow, typecheck, undefinedfilename Note: An undefinedfilename error occurs if the file does not exist.
