Hello, I have tested the ESQL for ODBC preprocessor with Firebird database, and it works perfectly. Thanks! I have a request. Esql add some comment rows to original source. These comments have an asterisk * at column 7. This is good for Cobol fixed format. But it not works with the modern free format. If the comments start from column 7, as now, and BEGINS WITH *> then they will work with fixed format and free format. Anyway, Esql is a great program. Thank to Sergey!
