Variable Declaration

In Lua, variables can be declared without explicit types, and the scope is determined by the context (local/global). In SAS, variables must be declared within a data step or a procedure, and their types are inferred from the data.

Lua Example:

local x = 10
y = 20  -- global variable

SAS Example:

data example;
    x = 10;
    y = 20; /* y is automatically a numeric variable */
run;

Control Structures

Lua and SAS have different syntax for control structures like if, for, and while. Lua uses then and end, while SAS uses do and end.

Lua Example:

if x > 10 then
    print("x is greater than 10")
end

SAS Example:

data _null_;
    if x > 10 then do;
        put "x is greater than 10";
    end;
run;

Functions and Closures

Lua supports first-class functions and closures, allowing functions to be passed as arguments. SAS has a different approach to functions, often requiring explicit definitions.

Lua Example:

function add(a, b)
    return a + b
end

result = add(5, 3)

SAS Example:

%macro add(a, b);
    %let result = %eval(&a + &b);
%mend;

%add(5, 3);

Table vs. Array Handling

Lua uses tables as its primary data structure, which can act as arrays or dictionaries. SAS uses arrays and datasets, which have different syntax and capabilities.

Lua Example:

myTable = {1, 2, 3}
print(myTable[1])  -- Output: 1

SAS Example:

data example;
    array myArray[3] (1, 2, 3);
    put myArray[1];  /* Output: 1 */
run;

References:

Error Handling

Error handling in Lua is done using pcall and xpcall, while SAS uses the ERROR statement and options to control error handling.

Lua Example:

local status, err = pcall(function() error("An error occurred") end)
if not status then
    print(err)
end

SAS Example:

data _null_;
    if 0 then set nonexistent; /* This will generate an error */
run;

References:

String Manipulation

String manipulation functions differ significantly between Lua and SAS, both in naming and functionality.

Lua Example:

local str = "Hello, World!"
print(string.sub(str, 1, 5))  -- Output: Hello

SAS Example:

data _null_;
    str = "Hello, World!";
    substr_str = substr(str, 1, 5); /* Output: Hello */
    put substr_str;
run;

References:

Object-Oriented Programming

Lua supports object-oriented programming through metatables, while SAS has a different approach to OOP, primarily through the use of the SAS/AF framework.

Lua Example:

Dog = {}
function Dog:new(name)
    local obj = {name = name}
    setmetatable(obj, self)
    self.__index = self
    return obj
end

SAS Example:

data Dog;
    length name $20;
    name = "Buddy";
run;

References:

Libraries and Modules

The way libraries and modules are imported and used differs between Lua and SAS, affecting how code is structured.

Lua Example:

local myModule = require("myModule")
myModule.myFunction()

SAS Example:

%include 'myModule.sas';
%myFunction();
