I want to create variable names automatically within a function (which are then used within this same function) that has been called by a script. As far as I am aware assign is unable to define variables within the workspace of the function.

Is there any neat solution to get round this? I do have a workaround but it is not very elegant. thanks Oli

You would use EVAL instead, but it is a bad idea to inexplicitly assign variables, whether by EVAL, ASSIGNIN, LOAD or whatever. Use dynamic fieldnames instead

S.('name1')=val1;
S.('name2')=val2;

etc... See also

This is a very frequently asked question, and the answer is easy: Do not do this. See FAQ: How can I create A1, A2, ... in a loop

Creating variables dynamically creates more problems as it solves. Beside the substantial decrease of the speed, the dugging is the main problem: It is hard to impossible to find out, what the program is doing when you read the code.
