Overview of Differences: MPE V/E and MPE XL Demand-paged virtual memory and a greater addressing range have caused modification to some intrinsics, but most MPE V/E file system intrinsics function the same in MPE XL. New services include access to mapped files through the Native Mode HPFOPEN intrinsic. Several MPE V/E file system features are not available on MPE XL based systems. New MPE XL features that are not available on MPE V/E include: * Mapped access to files (NM) * HPFOPEN intrinsic (NM) Changed Existing MPE V/E features that have been modified on MPE XL include: * Buffers and disk files * Disk file placement * Extents * File Codes * The following intrinsics: FCARD (CM) FCLOSE FCONTROL FFILEINFO FGETINFO FLABELINFO FOPEN FREADBACKWARD * FSETMODE FWRITE * PTAPE (CM) * MPE V/E intrinsics whose implementations are unchanged, but whose functionality may have changed due to peripheral dependencies. * The following commands: LISTF LISTFTEMP Not Used Existing MPE V/E features that are not supported on MPE XL include: * Foreign disk facility * Serial disk facility * The following intrinsics: FCARD (NM) PTAPE (NM) Unchanged Existing MPE V/E features that are the same on MPE XL include: * The following intrinsics: FCHECK FDELETE FDEVICECONTROL FERRMSG FLOCK FPOINT FREAD FREADDIR FREADLABEL FREADSEEK FRELATE FRENAME FSPACE FUNLOCK FUPDATE FWRITEDIR FWRITELABEL IODONTWAIT IOWAIT PRINT PRINTFILEINFO PRINTOP READ READX * LISTEQ command
