two files to one

[ketiv]

Hi
My device generated data.txt file.
When I generate the report, I moving data.txt to backup\'dtos(date())'.txt file, and clearing data.txt.
In this moment I have:
1. Report from device,
2. backup file in another folder,
3. Clear data.txt - which wait for new datas.

When I do it only once by day it's no problem, but when I must do it second time by day, a have a problem with existing (backup) file.

I have a question:
How to append two files?
For example:
data.txt and 20030526.txt to new 20030526.txt

I hope that it's clear

Ketiv,

From the DOS prompt type:

COPY 20030526.TXT + DATA.TXT
It will append DATA.TXT to 20030526.TXT

COPY 20030526.TXT + DATA.TXT NEWDATA.TXT
It will create a new file NEWDATA.TXT

this is piece of my code:

plik0 = "pool"
plik1 = "polln"

nazwa = 'backup/'+dtos(date())

COPY &plik0 + &plik1 &nazwa
DELETE FILE &plik0
FCREATE(plik0)

plik0 - file from my device,
plik1 - some test file.

But this not working :-(

Easiest way (but not the most elegent) is to make a temporary table with character fields 255 wide for however wide your reports can be and then append them both in type sdf and copy them over to a new text file type sdf.

Yes, I know
Second way is check if backup file exist, open it, and copy line by line datas from source file, but I looking for easiest method. I know that is possible, but I don't know how

How about a "one liner"?

xx=strtofile(filetostr("data.txt")+filetostr("20030526.txt"), "20030526.txt")

Or even shorter:

xx=strtofile(filetostr("20030526.txt&quot, "data.txt", 1)

No need to read 'data.txt' back in.

Dave this gives a new Data.txt, and his original "spec" specified a new 20030526.txt file! Perhaps he wants to keep Data.txt as a base.

Woops! I misread the original post. I was thinking the need was to append to 'data.txt'.

So, swap them:

xx=strtofile(filetostr("data.txt&quot, "20030526.txt", 1)
