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

[swpenney@xxxxxxxxxx]

Since finding out the work area is a dimension to hold 3000 entries 
(thanks to Njal !!), I found that the amount of data contained in the file 
would have brought it to 2999 thus trying to add more would have exceeded 
the limit.  So I've changed the value of WRKSPC-COUNT and WRKSPC-PTR to 
9999 to allow for extra records.  I've also changed the temporary work 
space size to 749941 to accommodate for this, but am still getting the 
MCH0601 only now it references Space offset X'00036F43' instead of Space 
offset X'00000000'.  Am I way off base here with the changes I've made or 
am I missing something else?

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






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?
