In a stacked environment (for example when COBSQL invokes another Integrated Preprocessor such as CP), COBSQL stores information
returned from the other Integrated Preprocessor in a side file that has an extension of STK. The file has the same basename
as the input file.
This message is displayed if COBSQL receives a COBOL error while trying to write out a record to the STK side file. COBSQL
also displays error message CSQL-E-023 (file I/O error) giving the COBOL I/O error message.
