There are several aspects of compiling and building applications that behave differently in
Visual COBOL. You might need to change the project properties and update some of the Compiler directives and settings that you previously
used.
Compiler directives When you upgrade your source code to Visual COBOL some Compiler directives that were specifically designed for 16-bit systems now produce an error on compilation because they
are no longer relevant. You should remove them from your code and directives files before you compile.
SQL Compiler Directive Options When you upgrade your to Visual COBOL, some SQL applications could require additional SQL Compiler directive options to avoid compiler errors.
XML PARSE Statement In Server Express, the default setting for the XMLPARSE Compiler directive is COMPAT, which causes the XML PARSE statement to return information
and events for IBM Enterprise COBOL Version 3. In Visual COBOL, the default is XMLPARSE(XMLSS), which returns information and events for IBM Enterprise COBOL Version 4.
