Hi:

I have a text file that has following format of the numbers

A1    B11:C11   B12:C12  B13:C13... (carrier return)
A2    B21:C21   B22:C22  B23:C23...  (carrier return)
A3    B31:C31   B32:C32  B33:C33...   (carrier return)
.....

A is interger (1-6 digits). B is xxx.xx or xx.xx. C is 1 to 5digits of interger. The goal is to read all of lines (it has different number of columns) and put them into a matrix. How to read all of the numbers here delimited with spaces and columns? Many thanks.

I've used the "{} Code" button to format the contents of the file. Did you see, that the auto-linebreaks of the forum made it unreadable? I cannot understand, why so many user do not care, if their question is not readable. Isn't it the vital interest of a question to be as easy to understand as possible?

What does " B is xxx.xx or xx.xx" mean? Does "C11" and "C is 1 to 5digits of integer" mean e.g. "1234511"? What exactly does "..." stand for?

Please post a small example of the real data.

You can try to use the import GUI (button on toolbar) to import the data and also generate a script that you can use as an example and use in the future. It's pretty simple to use. For instruction type "doc import tool" at the prompt.
