Writing to a CSV

Hi,

I have a processor with a processing time of 100 with an output to a sink. Using the OnEntry trigger for the sink I have the code:

fileopen("C:\Models\MachineShopFolder\Q1_03.csv");
fpt("HI");
fpr();
fileclose();


I let the model run 350 time units and I would expect to see three HI entries in the file- I see only one. Even when I leave off fileclose(); I see only one. I guess I’m new to writing data out to csv’s.

Gavin,
The fileopen command opens the file and erases the current content. You can add a second parameter to the fileopen command: fileopen("C:\\Models\\MachineShopFolder\\Q1_03.csv", "a"); This will append to the file instead of clearing.

My advice, however, would be to simply call fileopen once, at time 0 when the model starts, using a UserEvent, and then call fileclose using another UserEvent that fires on reset, so the file will be opened as soon as you start running the model, and will be closed the next time you reset the model.

Great!! Thanks ..........
