set

set() Function

Sets the value of a variable.

This function is rarely used because a simple assignment to a variable name can be used instead. However, using this function allows the first parameter to be a variable that identifies the variable name to be assigned.

Usage

[h: set(varName, val)]

Example

A simple use:

[h: set("test", 33)]
[r: test]

Returns

   33

A more sophisticated example that shows passing a string expression as the first parameter:

[h: var1="te"]
[h: var2="st"]
[h: set(var1+var2, 33)]
[r: test]

Returns

   33

Both of the above examples are equivalent to:

[r: test = 33]
