Origin Ver. and Service Release (Select Help-->About Origin):
Operating System: 8.1 , Win7
Dear all, Im using the filter option with a script to import and manipulate multiple files under origin. I have the following script commands to delete the first characters, but now I have long filenames where I would like the first x and and last y characters to be removed. Could anyone provide me with a easy way to do it?
%A = page.info.system.import.filename$; // get filename
%A = %[%A,#1,.]; // strip extension
length = %[%A]; //length of string
%A = %[%A,length-4:length]; // strip all but last 4 characters
win -r %H %A; // rename worksheet
delete -v length
Thank you very much in advance!

Hi,
In version 8.0 onwards we have added better string processing, so you can rewrite your code as below:
// Get filename to string
string str$=page.info.system.import.filename$;
// Remove extension
str$=str.getfilename(1)$;
// Get middle part by removing some chars from left and right
// Look for more such functions in documentation
str$=str.mid(4,8)$;
// Rename worksheet with truncated string
wks.name$=str$;

Thanks a lot, but Im not sure I get it.
If I have file eg. called
fr_xxxx_0_1491_ave_div_rebin.DAT
I wanted to remove the first 10 characters and the last 14, i.e I want 1492.DAT as the filename.
I tried the function:
str$=str.mid(10,14)$;
thinking that it would remove everything except the characetrs 10-14, but it doesnt work.
It simply takes the name of the worksheet and increment by one each time.
Could you please give me some more advice.

Hi,
The mid function is defined such that mid(n,m) says give me m characters starting at position n, see the definition here:
http://wiki.originlab.com/~originla/wiki/index.php?title=Category:String_and_Characters_%28Labtalk%29
So the following script will get you what you want:
// I'm defining a string whereas you will have the name by import:
string aa$="fr_xxxx_0_1491_ave_div_rebin.DAT";
// Define and assign the new string that you want:
string cc$ = aa.mid(11,4)$ + aa.right(4)$;
// Confirm:
type cc$;
1491.DAT
// Here is what you are currently getting, I guess:
string bb$ = aa.mid(10,14)$;
type bb$;
_1491_ave_div_
Hope this helps.
Vince

Dear Vince,
thanks a lot, I have tried the following code:
// Get filename to string
string str$=page.info.system.import.filename$;
// Remove extension
str$=str.getfilename(1)$;
// Get middle part by removing some chars from left and right
// Look for more such functions in documentation
str$=str.mid(11,5)$;
// Rename worksheet with truncated string
wks.name$=str$;
However, I cannot rename the file to what I want- it says:
"=page.info.system.import.filename$
string expression error!
AA:failed to add variable to local stack!"
Best regards

I tried your code and it worked fine for me. I think we can work in parallel here ...
Can you send us your filter (and which SR of 8.1), in case something is up there? (tech@originlab.com, attn: Vince, or follow the link at the top-right of this page)
Also, if you are running SR0--SR2, try patching to SR3, and try it again (in case of some earlier script bug):
http://www.originlab.com/Index.aspx?go=SUPPORT/ServiceReleases
In addition, I noticed that the error you get cites "AA," which is the name of one of the variables I defined in my sample code. Might my code have gotten mixed up with yours?
