- source
-
- This file contains the main SLATEC Fortran source of 1,078 routines. The
- subprograms are in alphabetical order with an *DECK (name) record as the first
- record of each subprogram. This *DECK record is compatible with the CDC and
- Cray update processors and the Opcode, Inc. HISTORIAN utility; it could be
- used as a search string for editing the file on other machines. The first deck
- is named AAAAAA and contains the SLATEC disclaimer.
-
- There are five (5) machine specific subprograms (D1MACH, I1MACH, R1MACH, FDUMP
- and XERHLT) in the source file. These are described further in the next two
- paragraphs.
-
- Machine constants, such as word length and maximum positive exponent, are
- supplied to routines in SLATEC source via the functions D1MACH, I1MACH and
- R1MACH. Make sure that each machine type at your site returns the correct
- values for these functions. In most cases, this only requires replacing a "C"
- with a blank in the first column of several lines of each function. The copies
- of D1MACH, I1MACH and R1MACH included in the source have all the machine
- specific constants commented out with a "C" in column one.
-
- The standard error handler has two machine dependent subroutines in it: FDUMP
- and XERHLT. The routine XERHLT is called via XERMSG when a fatal error is
- encountered and must terminate the job. The copy of XERHLT included in this
- file contains a "STOP" and thus does stop execution. However, in most
- circumstances, this normal exit is unacceptable when an error has been detected
- and this subroutine should be replaced at each site. The routine FDUMP is
- called via XERMSG when traceback information is desired. This routine should
- provide the traceback information to appropriate output files. The copy of
- FDUMP included in the source does not produce traceback information. If this
- function is desired, it must be implemented at each site.
-
- It is assumed that all ANSI-77 standard intrinsic functions are vendor-supplied
- and, therefore, are not included in the main SLATEC source. In the event that
- some of these subprograms are not resident on the system (e.g. DINT on CDC),
- many are included in the subsidiary programs, file 14. In some cases, the
- higher special functions (e.g. error functions, Bessel functions) anticipate
- that certain errors will be handled in the intrinsic functions. This may not
- be done appropriately in vendor-supplied intrinsic functions and may cause
- difficulties.
-
-
- quick_checks
-
- This file contains the SLATEC quick checks. There are thirty eight (38)
- quick check drivers.
-
- If some of the quick checks fail on certain machines, it does not necessarily
- indicate a problem in the source, but possibly in the quick checks themselves,
- or the machine architecture or the operating system or the compiler or vendor
- or user supplied software.
-
- Please note the following comments concerning this file and its contents.
-
- 1. The thirty eight (38) main programs (quick check drivers) are
- separated from the quick check subprograms. An *DECK (name)
- record was placed before each main program. The deck names are
- DECK0, DECK1, ... ,DECK37.
-
- 2. An *DECK (name) was placed before each test subprogram. The
- test subprograms are arranged in alphabetical order.
-
- On the VAX under VMS, the quick checks should be run with KPRINT = 0 or 1 (zero
- or one).
