handling arrays in macro

[Lucas, Falk /BDF HAM]

Hi,

is there any limitation in handling of arrays in the macro language???

I tried to call a function with 2 parameters, a number and an array,
which should return the array again.

FileArray=newArray(5);
...

FileArray=check_array(i,FileArray);

check_array(i,Array){
        if (i>Array.length-1){ //error message
                //create new temporary array
                temp= newArray(Array.length);
                temp= Array;
                //extend array size by 1
                Array= newArray(temp.length+1);
                //copy info from temp array
                for (x=0; x<temp.length; x++){
                        Array[x]= temp[x];
                }
        }
  return Array;
  }

This should extend the array dynamicly.

But I get an error message: Array expected at Array.length

Hi,

hmm, your sample code is missing a "function" definition in front of
check_array, however, this causes another error message.
If I add this and run the code it works here (for example when checking the
length I could successfully increase it from 5 to 6)

I use version ImageJ 1.37g
