Origin Ver. 7.5 and Service Release 6
Operating System: WinXP
Hello.
Here
http://wiki.originlab.com/~originla/wiki/index.php?title=LabTalk:Flow_of_Control#If.2C_If-Else
at the If-section is an example script. "The next script finds the first point in column A that is greater than 100."
But how is that working. As I understand. Origin is looking in Col(A)[1] if the value is greater than 100. If not ii becomes 2 and the script stops.
I need a script which gives me the point of a column where a specific value is stored.
For example: "data1_data(-2,2,0.01);" Where is for instance -1.95?
I tried with for and if and also with loop an if, but it is not working.
p=0;
loop (l,1,401)
{
if (data1_a[l]=-1.95) p=l;
};
p=;
Thanks |

You can use the colnum function in conjunction with the wcol function to get a column index from its name as in:
for(n = 1 ; n <= 10 ; n++)
{
wcol(colnum(A$(n)))[1] = n;
}

Thank you for your reply.
Now I have another simple question.
How can I access in a for-loop to columns named e.g. A1...A10.
For example that one is of course not working.
for (n=1;n<=10,n++){
data_a"n"[1]=1;
};
In this example in the first row of column A1 to A10 should be a 1.

Thank you for pointing out the bad script. Please check again for the updated version.

Note that there is a problem with your script :
if (data1_a[l]=-1.95) p=l;
which should read :
if (data1_a[l]==-1.95) p=l;
Also, to take advantage of the break command to short circuit the loop, you should use :
loop (l,1,401)
{
if (data1_a[l] == -1.95) break;
}
l=;
