Read Data from txt

[stutzbach]

Hello,

saving a file in excel as unicode text (*.txt). Is there an oppurtunity to read just one special column in a special row?
Perhaps someone could post an example code.I am trying for ours with deskriptors ... without success

maybe an example:

1234.00 2134.00 14.000
123.00 123.12 2343.00

how would the code look like for reading in 123.12?

READ(unit, 100)
100 Format (????)

Greeting Stutzbach

Assuming that the input file contains only numbers separated by blanks, and that every line contains the same number of entries,

real :: X,DUM
integer, irow = 2, jcol=2, ncol=3

open(unit,...,ENCODING='utf-8')
..
do i=1, irow-1
read(unit,*) ! rows 1.. (irow-1) skipped
end do
read(unit,*)((DUM,j=1,jcol-1), X) ! special value in row=irow, col=jcol
..

The value in the irow-th row and the jrow-th column will be in the variable X.

Unless you want to process implicit decimal points, etc., list-directed I/O is sufficient to do the job.

is there anyway to read a number of data that you don't know how much of them are in a row?
for example in unstructured grid there could be a mixes form of grids where there are triangle and squar elements, you don't know which element has 3 side and which has 4?
for example data are like:
3 4 10
20 11 30 12
8 5 2
19 13 29
21 9 2
......

however numbers in a row may differ but there is a maximum number of digits that can be in a row, for example they won't exceed N which will be determined somewhere else, how do you read this?
