C SUBPROGRAM:    MMAPTIME    GET MAP TIMES VARIABLES
C   PRGMMR: L. BENJAMIN      ORG: FSL        DATE: 06-09-08
C
C ABSTRACT: READ MAP START TIMES FOR ALL STATIONS FOR ONE 
C   VARIABLE AND TIME, AND CONVERT THEM TO ATIME-FORMAT 
C   CHARACTER STRING.
C
C PROGRAM HISTORY LOG:
C   06-09-08  L. BENJAMIN ORIGINAL VERSION (COPIED FROM MACARSTIME)
C
C USAGE:    CALL MMAPTIME (VCN,ATIME,NSTA,CDATA,STATUS)
C
C   INPUT ARGUMENT LIST:
C     VCN      - I       VARIABLE CODE NUMBER OF THE DESIRED DATA
C     ATIME    - C       YYJJJHHMM OF THE DATA TO BE READ
C
C   OUTPUT ARGUMENT LIST:
C     NSTA     - I       NUMBER OF STATIONS RETURNED
C     CDATA    - CA      ARRAY OF RETURNED CHARACTER DATA
C     STATUS   - I       0 - SUCCESS, OR ERROR CODE
C
C   INPUT FILES:
C     MADIS MAP NETCDF FILES FOR ATIME
C
C SUBPROGRAMS CALLED:
C     UNIQUE:    MERROR, MRDDBL, M_MKFNAM
C
C REMARKS:
C   THIS IS CALLED BY MGETMAPC, WHICH HAS ALREADY VALIDATED THE
C   CURRENT DATA SET IS MAP, THE VCN IS FOR A TIME VARIABLE, 
C   THE VARIABLE EXISTS IN THE CURRENT DATABASE, ETC.
C
C ATTRIBUTES:
C   LANGUAGE: FORTRAN-77 + EXTENSIONS
