cvhc(input.i1a.r, nchars.i4.v, output.i1a.r, istart.i4.v, fill.i1.v)
This routine converts a binary value, specified by INPUT, into ASCII
hexadecimal characters suitable for display. The characters are
loaded into output buffer OUTPUT starting at character position
ISTART (first character is postion 1). NCHARS contains the
length of the output string.
Note that INPUT can be arbitrarily long. It is assumed to have
exactly as many nibbles as there are NCHARS. Conversion proceeds
according to DEC numerical conventions. The first nibble of
INPUT, in the byte with the lowest address, gets converted to
the rightmost end of the output string. The last nibble of INPUT
gets converted to the leftmost character.
If either NCHARS or ISTART are not strictly positive CVH exits
