Eng:Creating Temporary Variables

Translate: - English 

Although there is no built in function for creating temporary variables while a project is running, it is possible to simulate it by using lists.

Creating Temporary Variables

To start out, make two lists, "Variables", and "Data". Then, make the following custom block:

define create variable (name)
add (name) to [Variables v]
add [0] to [Data v]

Setting Temporary Variables

Next, you need to be able to set temporary variables. There are two blocks, one for setting the value, and for changing the value, similar to Set () to () and Change () by ().

define set (variable) to (value)
if <[Variables v] contains (variable)> then //Check to see if the variable exists
set [i v] to [1]
repeat until <(item (i) of [Variables v]) = (variable)> //Find the index of the variable
change [i v] by (1)
end
replace item (i) of [Data v] with (value) //Replace the matching value with the new one
end

define change (variable) by (value)
if <[Variables v] contains (variable)> then //Check to see if the variable exists
set [i v] to [1]
repeat until <(item (i) of [Variables v]) = (variable)> //Find the index of the variable
change [i v] by (1)
end
replace item (i) of [Data v] with ((item (i) of [Data v]) + (value)) //Change the matching value
end

Retrieving Values

Because there is no way yet to make custom reporters a separate variable has to be set to the value wanted in order to actually use temporary variables in a project. The variable that contains the value will be called "Temp".

define get (variable)
if <[Variables v] contains (variable)> then //Check to see if the variable exists
set [i v] to [1]
repeat until <(item (i) of [Variables v]) = (variable)> //Find the index of the variable
change [i v] by (1)
end
set [Temp v] to (item (i) of [Data v]) //Set a readable value to the variable's value
end
