The function LOCB returns the absolute address of the variable given as its argument.
LOCF returns the absolute address measured in terms of Fortran machine words.
Structure:
FUNCTION subprogram
User Entry Names: LOCF, LOCB
Usage:
IAD = LOCB(X)where X is the name of a variable of any type, or a name declared EXTERNAL in the calling program.
IAD = LOCF(X)where X is the name of a variable of type INTEGER or REAL.
Notes:
On CDC, LOCF is included in the FTN library, and documented in the Fortran manual.
On all machines LOCF is intended to measure the displacement between variables, thus for example for:
COMMON /X/ M(12),A(4),LAST
N = LOCF(LAST) - LOCF(M(1))
N will be set to contain 16 on all machines, whilst
SPMquot LOCB(LAST) - LOCB(M(1)) " will give some multiple of 16.
