string - or function

hogi — Wed, 28 Jan 2026 14:52:46 GMT

In a code, the coding for the expression handling was wrong and produced a surprising result.

I reduced it to an interaction between "x()" [inside Variables (x(:column))] and a variable x.

an example:

x= "hello";
type(x); // -> string
X(5) // -> "hello"

After defining a variable x, I can use it as a function x(...) - with an arbitrary argument
... and JMP will return the content of x.

somehow the inverse of

col << rerun formula;
// short for 
col << rerun formula();
