LSAME LOGICAL Test if two characters are the same regardless of case

SLAMCH REAL Determine machine-dependent parameters

DLAMCH DOUBLE PRECISION Determine machine-dependent parameters

SECOND REAL Return time in seconds from a fixed starting time

DSECND DOUBLE PRECISION Return time in seconds from a fixed starting time

ILAENV INTEGER Checks that NaN and infinity arithmetic are IEEE-754 compliant

If you are working only in single precision, you do not need to install DLAMCH and DSECND, and if you are working only in double precision, you do not need to install SLAMCH and SECOND. These five subroutines and their test programs are provided in the files LSAMEF and TLSAMEF, SLAMCHF and TSLAMCHF, etc.

- Installing LSAME
- Installing SLAMCH and DLAMCH
- Installing SECOND and DSECND
- Testing IEEE arithmetic and ILAENV
