2.30 upgrade guide

Version 2.30 migration notes.

Report Writer

TOP Margin is ignored in compatibility reports.
TOP MARGIN is now ignored when ASCII reports are run in compatibility mode. Margins can be set by using the API function fgl_report_setPageMargins().
Parameter changed in fgl_report_configureCompatibilityOutput().
The reportName value for the fgl_report_configureCompatibilityOutput function is now automatically set to the name of the currently running report. When using the function, however, you must pass NULL as the value, for compatibility reasons.
4GL Boolean type is now interpreted as Numeric instead of String.
The 4GL Boolean type is now regarded as a Numeric type, instead of String as in previous versions. Existing expressions that contain references to boolean variables may require modification accordingly.
START REPORT syntax must be TO XML HANDLER.
The BDL statement START REPORT <repname> TO XML HANDLER handler is now the only valid syntax for starting graphical reports using a 4rp design document.
