Hi Loic,

 

Your file contains two bytes before the beginning of the string (0x01,
0x00).  These characters cannot be correctly parsed as a string type.

 

If you add y=mfscanf(2,fd4,'%c') before the reading of the strings, then you
find the first string in the vector is "Mesure" as expected.

 

There are more non-ASCII characters after the final string ("Alu"), which
cause the random extra strings at the end of your vector.  You can either
read a limited number from the file (first parameter not == -1), or discard
the last elements of the string vector.

 

There are lots of ways to make a single string from the vector.  One way is
s=sprintf("%s ",x).  The space after %s causes the elements to be separated
by a single space, if that's what you want.

 

HTH,

Mike.

Hello !

 

I try to read the characters in the attached ASCII file.

I would like to use the strings to make a legend in a graph.

 

I use the following code : 

fd4 = mopen("P_70",'r')

x=mfscanf(-1,fd4,'%s')

 

but I get : 

x  =

 

!                !

!                 !

!des              !

!A                !

!D                !

!                 !

!D                !

 

 

As you can see, the first word is missing and I don’t understand why.

Then I have not found how to convert x in a single string.

 

Many thanks for the help

 

Best regards

 

Loïc
