Evaluating variables @ runtime

5 posts in this topic

Hi

I have a set of variables var1, var2, var3, var4, var5 with values value1, value2, value3, value4, value5 respectively

The variable is being used in many places, hence I would not be able to convert them to an array.

I would want to read the values of the variables inside a for loop?

pseudo

For $i = 1 to 5

Msgbox( $(var + i)) --> which should give me the value of the variabl.

Next

Is the above scenario possible in Auto IT, How do I evaluate a variable name @ runtime.

To compare with javascript, which has an eval function. Does Auto IT has any such function?

Appreciating responses.

thanks & Regards

Mukund

Mukund,

Welcome to the Autoit forum. :)

an eval function. Does Auto IT has any such function?

Have you looked in the Help file? You might well find the answer there. ;)

The variable is being used in many places, hence I would not be able to convert them to an array

Would you care to elaborate on why using an array is impossible in your script? I can think of no reason why an array element cannot be used in place of a variable "in many places". :huh:

Thanks a lot moderators

1. I tried the eval function which was returning the value of the variable but I need the reference of the variable.

2. The variables have been referred directly in many places, so if I change it to an array, then I need to make lots of code changes. that was the reason to not to use an array.

And thanks a lot for the response, I found and Assign() function which helped me to evaluate a variable @ runtime and assign a value.

Regards

Mukund

Changing the variable names to an array is just a number of global changes away ...

If you use SciTE as your editor, there's a search and replace function that accepts a RegEx pattern for the search. So if your variables are named $var1, $var2, etc. The patterns you'd use are like this.

In the "Find What:" box you'd put $var(d+) and in the Replace with: box you'd put $var[1] and it would change all the $var names to $var[1], $var[2] etc.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.
