cvi4h DEPRECATED

	cvi4h(value.i4.r, nchars.i2.r, lbuf.i1a.r, start.i2.r [,fillchar.i1.r])

	This routine will convert a four byte integer value in the user's 
	variable 'value' into 'nchars' hex characters.  The characters will
	be placed in the user's byte buffer, 'lbuf', starting at the character
	position specified by 'start' (first character is position 1).

	value		value to convert
	nchars		number of characters to convert
	lbuf		returned ASCII buffer
	start		starting output character in 'lbuf' (starts at 1)
	[fillchar]	ASCII character to fill out buffer
			(default (NULL) is BLANK)

	This function requires the following include files:

	cnsparam_h, clib_h

	Related functions:

	numeric_to_ascii(_c), ascii_to_numeric(_c), cvh, ckcvh, cvhi4

	C/C++ usage:

	char	lbuf[NUM_CHARS];
	char	fillchar = ' ';
	short	nchars = NUM_CHARS;
	short	istart = 1;
	int	value;

	cvi4h(&value,&nchars,lbuf,&istart,&fillchar);
