CHARACTER * ( * ) FUNCTION AST_FORMAT( THIS, AXIS, VALUE )
*+
* Name:
* AST_FORMAT
* Purpose:
* Wrap up the C ast_format_a function.
* Language:
* Fortran 77
* Invocation:
* RESULT = AST_FORMAT( THIS, AXIS, VALUE )
* Description:
* This function is a wrap-up of the C ast_format_a function. It
* will rarely need to be used, but is provided for use on platforms
* where the normal mechanism for returning character strings as
* function results from C to Fortran (as defined in the f77.h
* include file) doesn't work.
*
* If this problem is encountered, the C macro NO_CHAR_FUNCTION
* should be defined (in CFLAGS) during C compilation. This will
* cause the function ast_format_a to be built (instead of
* ast_format) and this returns its result via an additional initial
* argument. This Fortran function is then used simply to transfer
* the argument value to the function result.
* Arguments:
* As for the C version of the Fortran-callable function ast_format.
* Returned Value:
* AST_FORMAT = CHARACTER * ( * )
* The character return value required.
* Notes:
* - The length of the returned result is limited to 100 characters
* by a local buffer. This length can be increased if necessary.

*-
* Type Definitions:
IMPLICIT NONE ! No implicit typing
* Arguments Given:
INTEGER THIS
INTEGER AXIS
DOUBLE PRECISION VALUE
* Local Variables:
CHARACTER * ( 100 ) BUFF ! Local buffer for result
*.
* Invoke the C function (with the additional argument).
CALL AST_FORMAT_A( BUFF, THIS, AXIS, VALUE )
* Return the argument value as the function result.
AST_FORMAT = BUFF
