ckcvic (ul_pccns)

	ckcvic(lbuf.i1a.r, istart.i4.v, nchars.i4.v, ivalue.i2.r, iok.i2.r)

	This routine will convert the number of decimal characters specified
	by NCHARS from the user's character buffer, LBUF, to an integer
	value in IVALUE.  The conversion starts at the character position
	specified by ISTART (first character is position 1).  If a null
	character is encountered the conversion will be terminated.  If a
	valid conversion was performed then the value of IOK is returned as
	zero.  Otherwise the position of the first "bad" character is
	returned in IOK as a negative value.
