Problems with attribute reverse in input statement

Hi all, My Society decided to upgrade from RDS 4.10 to 4.15 and from SE 5.00 to SE 5.07 and I' m now trying it because of all the problem we have had with the precedents versions (4.12 and 4.13). It seem to work but in same applications, when in input eg. " input by name ... without defaults " I call (with a function key) another function that have another input, when returning from the function, the field from which I pressed the F key comes in input but not reverse (obviously in the 4.10 version of RDS it was working and i recompiled all). In the main program I have the " OPTIONS INPUT ATTRIBUTE(REVERSE) " and I don't change it nowhere. What can I check ? Is this maybe a known bug. As anyone experienced any other difference or bug. Any suggestion would be appreciated. Thanks in advance Pierluigi "PIGI" Frullani Frumar srl pigi@frumar.it
