Error description
In rare cases, COBOL-compiled programs containing CALL statements with large numbers of parameters may be optimized incorrectly by ABO, resulting in incorrect parameters being passed to the target program. The problem is most likely to occur when there are multiple consecutive CALL statements to the same program with varying parameters. Symptoms may be "SQLCODE -310 DECIMAL HOST VARIABLE OR PARAMETER number CONTAINS NON-DECIMAL DATA", but other unexpected behavior, abends and wrong results are also possible. ABO was modified to correctly optimize programs containing CALL statements with large numbers of parameters.
