calculate from TXT file

[jeroen123]

Dear Oleg,
please help me out.

I have a txt file as below:
The first {value(0)} is the item number, the second {value(1)} is the sales in pce.

I want to know the total sales per itemnumber.

So I made a TEXT-loop; and within that loop a WHILE loop (while the {value(0)} equals itemnumber) a basicscript evaluate {sales} = {sales} + {value(1)
After this I can write a textfile with the total sales per item.

my question is: where to assign the first initial value of the first itemnumber of the textfile?
I cannot do AFTER the txt-loop; cause then it will change all the time
I cannot do before the txt-loop; cause the file has not been read by then...

Any clue?


81000,1,20,190
81000,15,17,5,190
81000,1,20,190
81000,1,20,190
81001,0,20,190
81002,1,20,190
81002,16,17,5,190
81002,1,20,190
81002,1,20,190
81002,1,20,190
81002,1,20,190
81003,1,20,190
81003,17,17,5,190
81004,1,20,190
81004,13,17,5,190
81004,1,0,190
81004,1,20,190

Very interesting task.
Typical algorithm is similar to my example. I hope this will help you.
Look at my example below:

a bit late;
but this works
Thanks!

dear Oleg;
I am working on this task,
now I try to calculate totals from a list of 1600 invoice lines, like:

00025019,17,3,7261,AG
00025019,11,3,7261,AG
00025019,11,2,7261,AG
00025019,22,11,7261,AG
00025028,22,4,9210,AG
00025028,17,3,9210,AG
00025028,10,1,9210,AG
00025028,17,5,9210,AG
00025028,21,3,9210,AG
00025028,9,1,9210,AG
00025028,9,0,9210,AG
00025028,34,7,9210,AG
00025028,34,10,9210,AG

Now halfway I get an error:

E: 10-10-2013 15:12:52: Error in expression "32762+8"
E: 10-10-2013 15:12:52: An error occurred. Step #28 (Evaluate berekenen verkoop totaal).

check calc.jpg (120.95 KiB) Viewed 19425 times

the black is the calculation RT make and data from RT; the red is the check calculation that I made in EXCEL:
untill row 145 all goes well (see the last columns calculation is zero difference)
then in row 146 it should add 84 but it adds just 33


at first sight it seems a very simple calculation: why error on this??
is there a maximum level to calculations?

[Oleg]

BASIC engine uses 16-bit integer values by default.
Integer values are from -32768 to 32767

If you use expression like "32762+8" then BASIC uses 16-bit INTEGER values and get overflow error.
You can use LONG (32-bit integer) or REAL (64-bit real number) datatype
In this case you should use such expressions

For LONG use 32762&+8& (symbol & says that basic must use LONG value)
For REAL use 32762#+8# (symbol # says that it is a REAL value)

In your task use expression like this:
{sales}#+{line(1)}#

Life is so simple if you know how

works!
Thanks!
