Use sys$parse to get the name part of the file specification. That is
in the above example, pick up "make" and return a copy of that string.
If something goes wrong in sys$parse (unlikely, this is a VMS/CRTL supplied
file specification) or if there is an empty name part (not easy to produce,
but it is possible) just return "make".
Somes notes ...
NAM[L]$M_SYNCHK requests a syntax check, only.
NAM is for ODS2 names (shorter parts, output usually converted to UPPERCASE).
NAML is for ODS2/ODS5 names (longer parts, output unchanged).
NAM$M_NO_SHORT_UPCASE may not be available for older versions of VMS.
NAML is not available on older versions of VMS (NAML$C_BID not defined).
argv[0] on older versions of VMS (no extended parse style and no
CRTL feature DECC$ARGV_PARSE_STYLE) is always in lowercase. */
