duke60,
User-defined ASCII date fields require leading Zeros in for the month and day values. So 1/2/93 is invalid, it would need to be 01/02/93 in this version of EZ-PnF. The requirement for leading zeros is specified in the Wizard screen for the date field definition step.
If that is a show stopper, I will have to address that option in future updates. I am open to suggestions for improvements...
Limits are a little trickier, I build the chart columns in memory, in a compressed format that depends on how many continuous X's or O's occur between column reversals or month characters within the column. You CAN force the column height to out of bounds by making the box increment smaller and smaller until the program returns a 'column too tall' message. As to the number of columns.. I get a little sneakier, I let the chart columns fill up the available memory, detecting this condition as it occurs. When it occurs, I start by deleting the first column, checking to see if there is enough room to add the new column. If there isn't enough room, yet, I delete the new 'first' column (it used to be column 2, but got left shifted when the original #1 got deleted). I repeat this process until the last price data record is processed and the last column of the chart has been inserted into the chart. But once again, the number of columns depends on the available memory, and that is a function of how tall each of the columns gets as well as how many of them there are. So, it make a long explanation short, I just don't know exactly what the limits are.
