String variable made with other variables?

[pognonec]

Hi list,

I want to write a Macro to create substacks with variables to define of the portion to cut out.
I have variable "b" and "e" that store the beginning and ending frames of the deletion needed.
I would like to store in a variable "d" the string:
b-e
so I can use this string variable to set-up the deletion needed in:
run("Make Substack...", "delete slices=&d");

I cannot get this variable d to store a string containing the b and e values with a dash in between...

Any suggestion would be appreciated.

Thanks,
Philippe

Try this:

  d = b + "-" + e;
  run("Make Substack...", "delete slices=" + d);

Or shorter:

  run("Make Substack...", "delete slices=" + b + "-" + e);

Hi Philippe,

In a classical macro way you would concatenate the sting directly like this:

run("Make Substack...", "delete slices=" + b + "-" + e);

Would this work for you?

Thanks Curtis and Christophe for your help.
Indeed,
run("Make Substack...", "delete slices=" + b + "-" + e);
does the job.
But I cannot set a variable string containing other variables to work. Curtis suggestion unfortunately does not work either. For example, if you try:
b= 10;
e = 2;
d = "b + "-" + e";
print(d)

You get an error on "-"
:-(

Dear Philippe,
You need to do:
b= 10;
e = 2;
d = b + "-" + e;
print(d)
My best regards,
Philippe

Hi,

As b and e are variable, they have to be outside the "".

b= 10;
e = 2;
d = b + "-" + e;
print(d);

will work. Or if you want to be really sure that it will be picked as a
string:

b= 10;
e = 2;
d = "" + b + "-" + e;
print(d);

Hi Philippe and Christophe,

I got tired fighting with that, and screwed up in my last answer. I did mean, as you suggested:
b= 10;
e = 2;
d = b + "-" + e;
print(d);

This is what does not work, "-" being error.

BUT Christophe's second proposal does work :-)
b= 10;
e = 2;
d = "" + b + "-" + e;
print(d);


Thanks to all!
Philippe
