[scilab-Users] can not read all words in a ascii file

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 !
! !
!points !
! !
!de !
! !
!transformations !
! !
!simple !
! !
!DSC !
! !
!Essai !
! !
!A !
! !
!Air !
! !
!Alu !
! !
! !
! !
!A !
! !
!A !
! !
!A !
! !
!A !
! !
!A !
! !
!D !
! !
!D !
As you can see, the first word is missing and I dont understand why.
Then I have not found how to convert x in a single string.
Many thanks for the help
Best regards
Loïc
