Valter, reports are stored in FRX files which are just DBF files. You can open an FRX file in the same way. You then need to locate the report object for which you want to change font size and change the FONTSIZE field for that record.

The best way to do this is open the FRX file from the IDE and examine it to understand how it looks. Find the field(s) that you want to manipulate - check the EXPR field of the FRX file.

If the report is included in your project you will need to copy it out at runtime to a temp file and change the temp copy. The copy in your project will be read only. eg In pseudo code:

*  Make a copy of my report in a temp location
USE MyReport.frx
COPY TO C:\TEMP\TempReport.frx

*  Change the font size
USE C:\TEMP\TempReport.frx
LOCATE FOR EXPR = MyField
REPLACE FONTSIZE WITH 10
USE

*  Use the temp report
REPORT FORM C:\TEMP\TempReport.frx PREVIEW


*  Optionally delete the temp report
DELETE FILE C:\TEMP\TempReport.*
