2 FORSYSDEF
 The FORSYSDEF.TLB text library of FORTRAN INCLUDE source was included
 as part of the FORTRAN V3.0 distribution from DEC.  As such this library
 will be maintained by DEC Software Services.  The modules currently
 in this library are:

 equivalenced to the appropriate bytes.  Also defines symbols for
 for the accounting record types.
3 $CRDEF

 Defines CR$_CRDEF_BITS(1) byte.
3 $DCDEF
 Definitions of symbols for VMS device classes and device types.
3 $DEVDEF
 Definitions bits in the device characteristics longword (as masks and
 offsets).  Defines the DEV$_DEVDEF_BITS(4) byte array.
3 $DMTDEF
 Definitions of option bits for the $DISMOU system service.
 Defines the DMT$_DMTDEF_BITS(1) byte.
3 $FORDEF
 Defines the FORTRAN completion status codes (32-bit longwords) for
 FORTRAN I/O errors (FOR$_... symbols).

 Also available in SYS$LIBRARY:FORDEF.FOR.

 the FOR$IOS_... symbols.

 Also available in SYS$LIBRARY:FORIOSDEF.FOR.

 $ENQ and $DEQ.
 Defines the LCK$_LCKDEF_BITSx(1) bytes.
3 $LIBCLIDEF
 Definitions for the LIB$ routines that use CLI callback services
 to enable/disable Ctrl-Y and Ctrl-T and define DCL symbols.
3 $LIBDCFDEF
 Definitions for the LIB$DECODE_FAULT routine.
 Defines the byte LIB$B_DCF_OPERAND(1).
3 $LIBDEF
 Defines symbols for the error status codes (LIB$_... symbols) returned
 from LIB$ routines.

 Also available as SYS$LIBRARY:LIBDEF.FOR.
3 $LPDEF
 Defines bits and fields of the line printer device-dependent
 characteristics.  Defines the LP$_LPDEF_BITS(4) byte array.
3 $MNTDEF
 Definitions of option bits and item codes for the $MOUNT system
 service.  Defines the MNT$_MNTDEF_BITS(3) byte array.
3 $MSGDEF
 Definitions of system message type codes (MSG$_... symbols) used
 with certain types of mailbox messages.
3 $MTDEF
 Magnetic tape device-dependent characteristics bits and fields.
 Also useful with magnetic tape I/O functions.
 Defines the MT$_MTDEF_BITS(3) byte array.
3 $MTHDEF
 Definitions of the MTH$_... error status code symbols signaled by
 the MTH$ routines.

 Also available as SYS$LIBRARY:MTHDEF.FOR.
3 $OPCDEF
 Defines the format of the buffer to pass to the $SNDOPR system
 service.  Also defines symbols for the operator request type
 codes and option bits.
3 $PQLDEF
 Defines the quota and limit type codes for the $CREPRC system
 service (PQL$_... symbols).
3 $PRVDEF
 Defines the bit offsets for the privilege mask longwords used in
 the $CREPRC system service (PRV$V_priv symbols).
 Defines the byte array PRV$_PRVDEF_BITS0(4).
3 $PSLDEF
 Defines the fields of the Processor Status Longword and symbols for
 the processor modes (PSL$C_mode for KERNEL,EXEC,SUPER,and USER).
 Defines the byte array PSL$_PSLDEF_BITS(4).
3 $RMSDEF
 Defines the RMS$_... symbols for the status codes returned by the
 VAX-11 RMS services.
3 $SECDEF
 Defines the section option bits for the $CRMPSC system service
 (the SEC$M_... symbols).  Defines the SECDEF$R_STRUCTURE1(23)
 and SECDEF$R_STRUCTURE2(32) byte arrays (?).
3 $SSDEF
 Defines the SS$_... symbols for the system status codes returned by
 the VMS system services.
3 $STSDEF
 Defines the fields of the VMS 32-bit status codes (aka condition
 codes) and the values of the severity levels.  Defines the byte
 arrays STS$_STSDEF_BITSx(4).
3 $TTDEF
 Defines the fields and constant values of the terminal device-
 dependent characteristics.  Also used for special terminal I/O
 operations with $QIO.  Defines the TT$_TTDEF_BITSx(4) byte arrays.
