I have a current row (row1) that has a start and stop time. I need to search the master file for the next row (row2) that has run time greater than 0. Once I have that row I need to take the stop time of row1 and subtract the start time of row 2. This will give me the time between when row 1 stopped and row 2 started. Any ideas how to do this in WebFocus? Thanks

Tracie,

You can do this in a DEFINE. You have to 'save' the contents of the row1 start and stop time and not overwrite them until some condition is met. Then don't calculate elaspsed time until runtime greater than 0.

Here is some pseudo-code that will possibly give you some ideas.

DEFINE FILE filename
CNTR/I8=CNTR+1;
CURRSTRT/I4=IF CNTR EQ 1 THEN STARTTIME ELSE CURRSTRT;
CURRSTOP/I4=IF CNTR EQ 1 THEN STOPTIME ELSE CURRSTOP;
ELAPSED/I8=IF RUNTIME GT 0 THEN 'calculate elapsed time';
END

This of course needs lots of work but might give you an idea of what you need to do.

Tracie,
What happens after you found row 2? do you look for row 3 and do the same calculation between 3 and 2?
Also, is your file sequential?

If this hypotheses is correct could this be your solution:

  
-* File tracie1.fex
DEFINE FILE CAR
RUNTIME/I5=IF SALES LT 10000 THEN 0 ELSE SALES;
START/D7=RCOST;
ENDT/D7=DCOST;
END
TABLE FILE CAR
PRINT COUNTRY CAR MODEL START ENDT RUNTIME
END
TABLE FILE CAR
PRINT COUNTRY CAR MODEL START ENDT RUNTIME
COMPUTE DIFF/D7=IF LAST ENDT EQ 0 THEN 0 ELSE START - LAST ENDT;
IF RUNTIME NE 0
END
