RE: [MI400] HELP...teraspace errors using MI code

[Njal Fisketjon <njal.fisketjon@xxxxxxxxxxxx>]

The MI program is handling using a temporary space as a work area.
It is dimension to hold 3000 entries of 75 bytes each + a 16 byte "header",
a total of 225016 bytes.

The SEARCH opcode is performing an array lookup to find the next unused
entry
and the code calculates it's offset in a slightly confusing way:
Rather than using
Current = (Entry_No - 1) * 75 + 16 the code is using the equivalent
Current = Entry_No * 75 - 59 (Because 75 - 16 = 59)

Can you confirm that the error occurs at instruction /43 and not
statement/line
no. 43?
