NAME

       AGCHNL - Provides a way for the user to substitute arbitrary character strings for the
       numeric labels generated by Autograph.

SYNOPSIS

        SUBROUTINE AGCHNL (IAXS,VILS,CHRM,MCIM,NCIM,IPXM,
       + CHRE,MCIE,NCIE)

DESCRIPTION

       IAXS        (an input expression of type INTEGER) is the number of the axis being drawn.
                   The values 1, 2, 3, and 4 imply the left, right, bottom, and top axes,
                   respectively.

       VILS        (an input expression of type REAL) is the value to be represented by the
                   numeric label, in the label system for the axis. The value of VILS must not be
                   altered.

       CHRM        (an input variable of type CHARACTER), on entry, contains the mantissa of the
                   numeric label, as it will appear if AGCHNL makes no changes. If the numeric
                   label includes a "times" symbol, it is represented by a blank in CHRM. (See
                   IPXM, below.)  CHRM may be modified.

       MCIM        (an input expression of type INTEGER) is the length of CHRM - the maximum
                   number of characters that it will hold.  The value of MCIM must not be
                   altered.

       NCIM        (an input variable of type INTEGER), on entry, is the number of meaningful
                   characters in CHRM. If CHRM is changed, NCIM should be changed accordingly.

       IPXM        (an input variable of type INTEGER), on entry, is zero if there is no "times"
                   symbol in CHRM; if it is non-zero, it is the index of a character position in
                   CHRM. If AGCHNL changes the position of the "times" symbol in CHRM, removes
                   it, or adds it, the value of IPXM must be changed.

       CHRE        (an input variable of type CHARACTER), on entry, contains the exponent of the
                   numeric label, as it will appear if AGCHNL makes no changes. CHRE may be
                   modified.

       MCIE        (an input expression of type INTEGER) is the length of CHRE - the maximum
                   number of characters that it will hold.  The value of MCIE must not be
                   altered.

       NCIE        (an input variable of type INTEGER), on entry, is the number of meaningful
                   characters in CHRE. If CHRE is changed, NCIE should be changed accordingly.

USAGE

       This routine is not called by the user program, but by Autograph itself, just after the
       character string representing each numeric label has been generated and just before it is
       written on the graph. The user may change the character string in any desired way. Axes
       may thereby be labeled using the names of the months, Roman numerals, etc.

       Note:  A user version of AGCHNL should not call any other Autograph routine.

ACCESS

       To use AGCHNL, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably
       in that order.
