2.9.107 FTXBXSReusable
The FTXBXSReusable structure is used within the FTXBXS structure when it describes a spare structure that can be reused by the application and converted into an actual textbox. An FTXBXS structure can become reusable when the shape is deleted or linked after another shape in a chain. Additionally, the final FTXBXS structure in a PLC is reusable. All reusable FTXBXS structures in a PLC are part of a single chain, with the last FTXBXS structure in a PLC being the first item in the chain.

iNextReuse (4 bytes): An integer that specifies the index of the next reusable item in the chain. If this is the last FTXBXS structure in the chain, this value MUST be -1. Otherwise, this value MUST be non-negative, and MUST be less than the number of FTXBXS structures in the PLC. Furthermore, the FTXBXS structure at that index MUST be flagged as reusable, and MUST have a cReusable value that is 1 less than the cReusable value from this structure.
cReusable (4 bytes): An integer that specifies how many reusable FTXBXS structures are in the chain after this one. If this is the last FTXBXS structure in the chain, this value MUST be 0. Otherwise, it MUST be greater than zero, and MUST be less than the number of FTXBXS structures in the PLC.
