User input for a global variable in a macro?

[Bill Mohler]

Can a macro be used to define a global variable for other macros
within the same file?  In other words, can a macro request a number
from the user in a dialog and then set assign that value to a global
variable?  Or can global variables in macros only be hard-coded into
the text of the macro file?

Thanks,
Bill

Bill,

If I understand you correctly, then yes you can set global variables for
a set of macros. You define the variables at the beginning of the macro
outside any of the installable submacros.  An example:

var myNewVariable = "Hi Bill";

macro "Read [1]"{
        Dialog.create("Enter Text");
        Dialog.addMessage("Enter some text");
        Dialog.addString("Text:", myNewVariable, 12);
        Dialog.show();
        myNewVariable = Dialog.getString();
}

macro "Write [2]"{
        print(myNewVariable);
}

Cheers

Mike

Moving the initial declaration to the head of the file completely
solved my problem. Thanks!

Related to this, I have a macro using:

Dialog.create("Intensity values");
Dialog.addNumber("C1min:", 2);
Dialog.addNumber("C1max:", 10);
Dialog.addNumber("C2min:", 2);
Dialog.addNumber("C2max:", 10);
...
Dialog.show();

a = Dialog.getNumber();
b = Dialog.getNumber();
c = Dialog.getNumber();
d = Dialog.getNumber();
....

As shown, each time I run the macro, the default values '2' and '10' are shown in the dialog box. Is there any way that the macro, when it runs the next time, replaces/recalls these values with the last user input (i.e. a, b, c, d, ....)?

Thx, Marcel

Hi!

I've done this by writing all settings in a string seperated by
";" ("value1;value2;...;valueN") and then writing it to a file
(File.saveString(...)) in the ij temp directory.

When I start the macro I restore the old values out of that file:
oldsettingsRAW
=File.openAsString(getDirectory("temp")+"mysettings.txt");
roidata = split(roidataRaw, ";");

value1 =  parseInt(roidata[0]);
value2 =  parseInt(roidata[1]);;
etc.

Cheers,
Thorsten

Try this.  It should work until the macros are reinstalled at which time they will be reset to the initial values.

// defined as globals at the very beginning

var a = 2;
var b = 10;
var c = 2;
var d = 10;

macro "Test globals" {

  Dialog.create("Intensity values");
  Dialog.addNumber("C1min:", a);
  Dialog.addNumber("C1max:", b);
  Dialog.addNumber("C2min:", c);
  Dialog.addNumber("C2max:", d);
  Dialog.show();

  a = Dialog.getNumber();
  b = Dialog.getNumber();
  c = Dialog.getNumber();
  d = Dialog.getNumber();

  print(a,b,c,d);
} // end macro

Thanks - Michael Cammer's method works best for me, as I always got an "access denied' error message using jumpfunky's method (despite the saving-location being accessible)
