R1. Machine-dependent constants
I1MACH-I Return integer machine dependent constants.
R1MACH-S Return floating point machine dependent constants.

R2. Error checking (e.g., check monotonicity)
GAMLIM-S Compute the minimum and maximum bounds for the argument in
DGAMLM-D the Gamma function.
R3. Error handling
FDUMP-A Symbolic dump (should be locally written).
R3A. Set criteria for fatal errors
XSETF-A Set the error control flag.
R3B. Set unit number for error messages
XSETUA-A Set logical unit numbers (up to 5) to which error
messages are to be sent.
XSETUN-A Set output file to which error messages are to be sent.
R3C. Other utility programs
NUMXER-I Return the most recent error number.
XERCLR-A Reset current error number to zero.
XERDMP-A Print the error tables and then clear them.
XERMAX-A Set maximum number of times any error message is to be
printed.
XERMSG-A Process error messages for SLATEC and other libraries.
XGETF-A Return the current value of the error control flag.
XGETUA-A Return unit number(s) to which error messages are being
sent.
XGETUN-A Return the (first) output file to which error messages
are being sent.
