read multiple data

zxu4 · ‎05-08-2006

Hi,
I tried to read multiple data from one line in my datafile.

Data format is :

0.3,0.9,1.2,2.3

Comma is used to separate each of them, but I don't know how many in one line. I want to use an array to read all of them, like,

read(10,'(f5.2)')value(1),value(2),...

How to make it happen to my array value?

Thanks!

Roy

Pasted from CVF help found using 'comma' in the 'Index':

Code:

Using Commas to Separate Input Data

You can use a comma to terminate a short data field. 
The comma has no effect on the d part (the number of 
characters to the right of the decimal point) of the specification.

The comma overrides the w specified for the I, B, O, Z, F, E, D, 
EN, ES, G, and L edit descriptors. For example, suppose the 
following statements are executed:

       READ (5,100) I,J,A,B
  100  FORMAT (2I6,2F10.2)

Suppose a record containing the following values is read:

1, -2, 1.0, 35

The following assignments occur:

I = 1
J = -2
A = 1.0
B = 0.35

A comma can only terminate fields less than w characters long. 
If a comma follows a field of w or more characters, the comma 
is considered part of the next field.

A null (zero-length) field is designated by two successive 
commas, or by a comma after a field of w characters. Depending
on the field descriptor specified, the resulting value assigned 
is 0, 0.0, 0.0D0, 0.0Q0, or .FALSE..
