This routine will figure out the path-name of the executing image. On the VAX this is done with a system call, on UNIX by scanning the search path until it finds the module whose name is in argv[0].
Structure:
SUBROUTINE subprograms
User Entry Names: WHOAMI
Common Blocks: COMMON /SLATE/ ND,NE,NF,DUMMY(37)
Usage:
CALL WHOAMI(NAME)On exit, NAME contains the full path-name of the module.
Status and various lengths are returned in /SLATE/:
ND = 0 if the call failed,
> 0 the number of characters in the path-name
On the VAX:
ND = number of characters in the path-name with .EXE;n stripped NE = number of characters before the semicolon, NF = number of characters in the complete name.For example:
if NAME is DISK:[CERN]WYLBUR.EXE;4
_:.=+=.: 1_:.=+=.: 2_:.=+=
we will get ND=17, NE=21, NF=23.
Note: At the moment this is available only on the VAX; the code
exists for UNIX but is not yet in the library.
