SUBROUTINE GRIDA(IER)
C
C PURPOSE To provide a simple demonstration of
C all of the entry points of the GRIDAL
C package. Eight plots are produced.
C
C USAGE CALL GRIDA (IERROR)
C
C ARGUMENTS
C
C ON OUTPUT IERROR
C An integer variable
C = 0, if the test was successful,
C = 1, otherwise
C
C I/O If the test is successful, the message
C
C GRIDAL TEST EXECUTED--SEE PLOTS TO CERTIFY
C
C is printed on unit 6. In addition, 8
C frames are produced on the machine graphics
C device. In order to determine if the test
C was successful, it is necessary to examine
C these plots.
C
C PRECISION Single
C
C LANGUAGE FORTRAN 77
C
C ALGORITHM All of the entries of the GRIDAL package
C are invoked (GRID, GRIDL, PERIM, PERIML,
C HALFAX, TICK4, LABMOD, and GRIDAL) to
C produce plots. The GRIDAL entry is called
C ten times. The first call is to demonstate
C a full frame grid. The next nine calls
C create a single frame that contains the
C nine legal IGPH grid options to show how
C up to nine plots can be placed on a single
C frame.
