Macro language question

[Wolfgang Schechinger]

Dear experts,

I would like to use the loop variable of a for...next construct as part of a filename, which should look like file[number].txt

How to achieve that? Is there something like the STR$(var) command from BASIC to convert numbers into strings?

Many thanks,

Wo

Have a look at the macro language documentation, the function you're looking
for is d2s :

Hi,

You should be able to direct "pasting" as ImageJ's interpreter will  
cast the number to string like this...

for (i=0; i<5 ;i++) {
        f = "myfile_" + i + ".txt";
        print(f);
}


But you can also use the macro function toString().  See ... http://
rsb.info.nih.gov/ij/developer/macro/functions.html#T

Cheers,
Ben

Hi Wo,

as in Java, in a script the "+" operator is overloaded to concat strings
and numbers will automatically be converted to strings, so you can simply
do

for (i = 0; i < n; i++)  {    // Or similar
...

      name = "file"+i+".txt";

...
}

Cheers

Joachim
