Calling a sql server store prodcedure from AcuCOBOL

Hi,

I created a stored procedure in sql server, and trying to call it from AcuCOBOL but getting this error:

Could not find stored procedure 'sp_test'    42000

It does exist in sql server, with all rights granted.

Calling code looks like this:

EXEC SQL

  DECLARE CURSOR-SP CURSOR FOR

    :ret-code = exec sp_test

END-EXEC

It's a bit confusing as 42000 means acuodbc driver expected, but I'm using the acusql driver, not ODBC
