Well, the standard algorithm is to determine the length of the string and then obtain a 1-character sub-string beginning at that position.

See:
DEFINE FILE CAR
CARV/A30V = CAR;
CARV_LEN/I4 = ARGLEN(LENV(CARV, CARV_LEN), CARV, CARV_LEN);
CARV_LAST_CHAR/A1 = SUBSTV(CARV_LEN, CARV, CARV_LEN, 1, CARV_LAST_CHAR)
END
TABLE FILE CAR
PRINT CAR
      CARV
      CARV_LAST_CHAR
END

quote:
from a variable length string

CARV is just an AnV representation of CAR to simulate your case.

Hope that helps!

I am being happy now, I remember I do copy of function for library - here be it -

DEFINE FUNCTION RIGHT(SOURCE/A999, CHARS/I3, X_FMT/A4)
  C_LEN/I3     = ARGLEN(999, SOURCE, 'I3');
  C_FMT/A4     = 'A' || EDIT(C_LEN);
  RIGHT/A999V  = REVERSE(CHARS,REVERSE(C_LEN,SOURCE,C_FMT),X_FMT);
END
TABLE FILE CAR
SUM COMPUTE LAST_TWO/A2 = RIGHT(COUNTRY, 2, 'A2');
   BY COUNTRY
END
TABLE FILE GGSALES
SUM COMPUTE CARDINAL/A4 = RIGHT(REGION, 4, 'A4');
   BY REGION
END
The someone be Tony A, I remember now Smiler Search not work still Frowner
