About split function

[Luis Isaac Ramos Garcia]

    Dear community;

    I would like to split into an array a list of 58 numbers that appear
in a line in the Image Info. In the line the numbers are joint by "\",
for example:

 -15\-15\-15\-15\-15\-15\-15\-45\-45\-45\-55\-55\-25\-55\-75\-75\-65\-65\-65\-55\-35\-35\-5\-5\-5\-5\-5\-5\-5\-15\-15\-15\-15\-15\-15\-15\-15\-15\-15\-15\-15\-15\-5\-5\-5\-5\-5\-5\-5\-5\-5\-5\-5\-5\-5\-5\-5\-5

    The problem is that in use the following sentence in macro language:

    a=split(TxT,"\");

    I receive an error.
    The problem is in the "\", because if I use or example "5", I have
no problem to split the line, obviously getting incorrect results.

    What is wrong in the use of "\"?

    Many thanks,

Dear Luis,

\ is used for reserved characters, such that \n is for a line break, etc.
so \ by itself is a reserved character, so you have double it in a
string ("\\").
In other terms, the character "\" has to be written "\\" when using strings.

    Many thanks, Christophe;

    I have another basic question.

    If I would like to divide this array in two, i. e.:

 Line=-15\-15\-15\-15\-15\-15\-15\-45\-45\-45\-55\-55\-25\-55\-75\-75\-65\-65\-65\-55\-35\-35\-5\-5\-5\-5\-5\-5\-5\-15\-15\-15\-15\-15\-15\-15\-15\-15\-15\-15\-15\-15\-5\-5\-5\-5\-5\-5\-5\-5\-5\-5\-5\-5\-5\-5\-5\-5
 AA=split(Line,"\\");
 for (i=1;i<=29;i++){
        A1[i]=AA[29-i];                  //...
        A2[i]=AA[59-i];
  }

    The debugger says that "Undefined Identifier in line ..."; I thought
that there is no need to define variables like A1, A2. And In this case
how can I define the identifiers?

    Thanks again,
