cvn(value.i2.r, nchars.i2.r, lbuf.i1a.r, start.i2.r, 
	    radix.i2.r [,fillchar.i1.r])

	This routine will convert a two byte integer value in the user's 
	variable 'value' into 'nchars' ASCII 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).
	The radix of the conversion is given by 'radix'.

	value		value to convert
	nchars		number of characters to convert
	lbuf		returned ASCII buffer
	start		starting output character in 'lbuf' (starts at 1)
	radix		radix to use for the conversion
			(values should be between 2 and 36)
	[fillchar]	ASCII character to fill out buffer (default is BLANK)

	This function requires the following include files:

	cnsparam_h, clib_h

	C/C++ usage:

	char	lbuf[NUM_CHARS];
	char	fillchar = ' ';
	short	value;
	short	nchars = NUM_CHARS;
	short	start = 1;
	short	radix = 10;
