* CLI problem ...
* SQLBindParameter architecture appears broken for I/O params. This CLI API
* uses last parameter 'bind_len' to control both in and out lengths.
* While bind_len=NTS seems obvious answer, it does not work mismatch in/out sizes.
* I/O example bind_len=NTS (implicit conversion decimal<>char):
* Input: smaller '2.22', implies user buffer max implicit conv length 4 (input len = 4).
* Output: stored proc output returns a larger value '111.11' (output len = 6).
* Result: value truncation will occur '111.' (... people notice losing their pennies).
*
* SQLBindParameter future solution (proposed) ...
* 1) Interface needs a 'max size' (out) and 'current size' (in) to work for I/O.
* Note: There is an unused parm in SQLBindParameter maybe use for 'output max'.
* 2) Alternatively, new data types like SQL_CHAR_NULL_TERM to pass bind_len=max
* with 'understanding' database implicit conversion 'null term' contract.
*
* Today, work around SQLBindParameter ...
* We/middleware need allocate full size buffers with INOUT and OUT params
* using bind_len=max to avoid truncated results seen using bind_len=NTS
* (we must pad).
*
* Unfortunately, 'pad' is language dependent ...
* LUW typical stored proc:
* Languages like c use NULL terminated strings,
* therefore extended string buffers can be pad zeros (0x00).
* IBM i typical stored proc:
* Languages like RPG or Cobol rare use null terminated strings,
* therefore end of data pad expected to be pad 'spaces' (0x20).
* Of course, 0x20 pad means strip after SQLExecute (argh).
