cve DEPRECATED

       cve(value.r4.r, nchars.i2.r, lbuf.i1a.r, istart.i2.r)

       This routine converts a single precision floating point value in the 
	caller's variable 'value' into 'nchars' ASCII characters in E-format
	(-1.23E+01).  The characters are placed in the user's byte buffer 
	'lbuf' starting at character position 'start' (where first character 
	is 1).  The caller's variable 'value' is rounded prior to conversion 
	based on the 'nchars' specified (nchars - exponent).  The number of 
	characters 'nchars' has a range from 6 - 16 and includes sign, whole
	digit, decimal point, fractional digits, and exponent.  The return 
	buffer is filled with stars (*) to indicate overflow.
