Origin Ver. and Service Release (Select Help-->About Origin): 8.5
For example, I have the following code:
del col(C);
wks.addcol(C);
col(C)[C]$="sum/N";
The Origin help files said that if wanna call this, then the code must start with (for instance): void myfunc(), so I added:
void myfunc()
del col(C);
wks.addcol(C);
col(C)[C]$="sum/N";
then in the script window, I type "myfunc", but "Command error" appears.
Question:
So How do I call the code please?
Thank You!

Yes, for basically a procedure, you are better off using ogs sections.
Functions are useful when you need a return value, and when you need to pass in arguments that are not easy to achieve with %1 %2 etc.

[Main]
del col(C);
wks.addcol(C);
col(C)[C]$="sum/N";
Save this code as "func2.ogs" in my User Files folder.
Then in the script window type "run.section(func2, Main)".
Yes, yes, this works even more convenient.
Thank you very much,SteffenG and cpyang!

We greatly appreciate EigenGoofy's sharing of info and we will work on fixing that wiki page.
One thing definitely true is that ogs file name should not be the same as LT Function name since ogs files in user folder can be executed by name (calling the [main] section if present), see
http://wiki.originlab.com/~originla/wiki/index.php?title=Script:From_Files#Running_an_OGS_File
But one key think not mentioned in that wiki is that spaces in the ogs file name is striped, so the myfunc will execute "my func.ogs".
We can certainly change the precedence order to allow LT function higher precedence to avoid this confusion in future versions.

If you want to use OGS-files you have to take the run.section-method. You will find help for this in the LabTalk-Help under topic 'run'.
Best regards,
Steffen

This can not work.
Save the following code as "my func.ogs":
function myfunc(){
del col(C);
wks.addcol(C);
col(C)[C]$="sum/N";
}
then in the script window, type "myfunc".
it returns "Command error".
Thank You!

By the way, based on my last post, the following address provides insufficient help:

It works, Thank You, cpyang!
Actually, you only give me a PARTIAL answer. There are at least 3 unsolved problems. Luckily, I solved all of them
If saving the following code as "myfunc.ogs" in the folder User Files
@global=1;
function myfunc(){
del col(C);
wks.addcol(C);
col(C)[C]$="sum/N";
}
then type "myfunc" in the script window, it will return "command error".
Solution: after saving this code as an ogs file, we have to completely exit Origin, before calling the function in the script window, otherwise it won't work.
After rebooting Origin, then in the script window type "myfunc", it does not appear "command error", but just nothing happens. type "myfunc" again, nothing happens again.
Solution: This is a naming problem, we can not name the file as the same as the name of the calling function. Let's rename "myfunc.ogs" by "myfunc1.ogs".
Aftering restarting Origin again, type "myfunc" in the script window. it appears "command error".
Solution : we have to type "myfunc1" first, at this time, it does not return "command error", then type "myfunc", up to now, it successfully calls my function!
Thank You again, cpyang! |

Hello, SteffenG
This can not work.
Save the following code as "my func.ogs":
function myfunc(){
del col(C);
wks.addcol(C);
col(C)[C]$="sum/N";
}
then in the script window, type "myfunc".
it returns "Command error".
Thank You!

you have to enter first the keyword 'function' and put the code of the function inside brackets like:
function myfunc(){
del col(C);
wks.addcol(C);
col(C)[C]$="sum/N";
}
The keyword 'void' does not exist in LabTalk.
