What is the CALL statement?

The CALL statement is used in programming to invoke a procedure or function. It allows you to execute a block of code defined elsewhere in your program. When the CALL statement is executed, control is transferred to the specified procedure or function, and after its execution, control returns to the point immediately following the CALL statement.

In languages like C, you would typically call a function by simply using its name followed by parentheses, like this:

#include <stdio.h>

void greet() {
    printf("Hello, World!\n");
}

int main() {
    greet(); // This is where the CALL happens
    return 0;
}

In this example, the greet() function is called from the main() function, which executes the code within greet() when the CALL is made.
