In a similar situation, I used a typed local constant: this could be
used as a buffer, persisted, did not cause additional stack memory to
be allocated, and could only be accessed in the single procedure it
was attached to.

It was a bit kludgey, I admit, but given the stack linitations in Turbo,
I think it qualified as a necessary bit of hacking.
