set() Function
• Introduced in version 1.3b48
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)]Parameters
varName- Variable name or a string containing a valid variable name.val- The value to set the variable to.
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]
