INTEGER FUNCTION INTIN( HPARN, INTV, REALV, CHARV)
C
C---->
C**** INTIN
C
C Purpose
C -------
C
C Change input field parameters in common block.
C
C Interface
C ---------
C
C Input
C -----
C
C HPARN - MARS parameter name.
C INTV - MARS parameter value(s) (Integer).
C REALV - MARS parameter value(s) (Real).
C CHARV - MARS parameter value(s) (Character).
C
C
C Method
C ------
C
C Recognise MARS paramter and reset appropriate common
C variable value(s).
C
C Uses environment variable ISLSCP_OLD_LSM to locate old
C land-sea mask GRIB product file. If the variable is not set,
C uses /home/ma/emos/data/islscp_old_lsm.
C
C
C Externals
C ---------
C
C JDEBUG - Check if debug switched on.
C IBASINI - Check basic initialisation of common blocks is done
C CHEQUAL - Compare two ASCII strings without regard to case.
C INTLOG - Log error message.
C JMALLOC - Dynamically allocate memory
C JFREE - Free dynamically allocated memory
C GETENV - Get value of an environment variable
