How can I create string variables?

I have a featurescript feature that takes a string as a precondition.
Is it possible to define a variable that is a string that I can pass into this feature?

I've tried setting the value of a variable to be something quoted in double quotes and single quotes, neither of these is accepted.

    as far as I know you can't set string value to a part studio variable, but you can pass to feature script the name of a variable as string

    Hmm, okay then, I've added the feature request tag. This would be really useful for me.

    There is work in progress to remove the type restrictions on variables, so our intent is that you will be able to use strings, arrays, maps, even functions (lambdas).

    @ilya_baran Lambda functions in variables... this sounds fun!

    @leon_poot You can already put a lambda into a variable with a custom feature.  What we plan to add is the ability to put it in a variable in a Part Studio directly.

    nice

    will that mean we can have logical if statements (if..else..while) inside the variable's lambda function?
    or is the lambda function limited?

    I've rarely used lambda's in C#, so they are still kinda short hand (in-line) tricks to me...

    The lambda can contain arbitrary FeatureScript code (so yes, if-else, loops, variables).  Though if you are going to be defining non-trivial lambdas, I would recommend putting them in a custom feature, like this: https://cad.onshape.com/documents/9307925f33961a9f1b10c559/w/8cd40e21db8c1060b315e72f/e/0801bef9707f10c6cf75635f
