Informix-4GL 4.10 bugs

I am having a problem with the 4GL 4.10 and would like to know if anyone knows the solution for this. I call the Informix Tech Support and the person tells me that it is a known bug for this version of 4GL and there is no work-around. The problem is: In my screen form, I have a screen record of 5 [A |B |C ] [A |B |C ] [A |B |C ] [A |B |C ] [A |B |C ] say A is the 1st field-name, B is the 2nd, C the 3rd. Then in my 4GL problem, I want to do the input statement from line 1,2,3,4, or 5 depending on the userid. For example, when I run the input statement on the 3rd line, my input statement will be like this: input rec.* from sc_rec[3].* after field A if error_occur() then next field A <--- program stops here end if end input Then when I run the program, it generates an error message -1119 means that the next field A is not on the screen form but field A is indeed defined in the form. The after field statement recognizes the field-name A but the next field statement does not. When I change my input statement to input by name rec.* ... it works OK. Then I compile the same problem on our old machine running 4GL 1.10, it does not give me any error. So it must be 4GL 4.10. Does anyone have this problem w/ their 4GL 4.10? I am running Online 5.01 on SunSparc 670. Thanks in advance. Tony Chow.
