Assignment Errors (Compiler Errors 1400 to 1402)
Compiler Error 1400
assignment error: Illegal Assignment
Assignments in SIMPL+ require that the value being assigned to a variable must
equate to the same type as that variable. Integer variables can only be assigned
integer values and string variables can only be assigned a string value.
•
If a complex assignment is being made, make sure that all parenthesis are matched.
In other words, all opening parenthesis must have a matching closing parenthesis.
•
When comparing 2 strings (‘=’, ‘<’, ‘>=’, etc.), the resulting value is an integer
•
Input variables (DIGITAL_INPUT, ANALOG_INPUT, STRING_INPUT and
BUFFER_INPUT) cannot be assigned a value.
The following are examples of this error:
INTEGER x, y;
STRING str[100], str2[100];
DIGITAL_INPUT digIn;
DIGITAL_OUTPUT digOut;
ANALOG_OUTPUT anlgOut;
FUNCTION MyFunc()
{
str = “abc”; // ok
str = “abc” + “def”; // ok
str = str2; // ok
x = 1; // ok
x = digOut; // ok
x = (str = str2); // ok
x = 5 * (1 + (str > str2)); // ok
digOut = x; // ok
digOut = 5; // ok
digOut = anlgIn; // ok – both are integer types
x = str; // error – str does not equate to
// an integer
// atoi() should be used
digIn = 1; // error - digIn is an input variable
str = 5; // error – 5 is an integer
// MakeString() should be used
str = str2 = “abc”; // error = str2 = “abc” is an
equality
// test, not an assignment
