Expression Type Mismatch

What does 2249 mean?

This error typically arises when an expression, particularly a counter in a counting loop, is not of the required INT data type. It is often a consequence of a missing variable declaration. The KRL compiler expects counting loop counters to be explicitly declared as INT, and this mismatch prevents correct program execution.

• An expression's result type does not match the expected type for its context.
• Arithmetic or logical operation produced an unexpected data type.
• Type incompatibility in assignment between an expression and a variable.
• Function return type mismatch with variable declaration.
• Error in comparing or combining values of different data types.

1. 1

   Open the source file (e.g., 'ERROR.SRC') in the editor.

2. 2

   Locate the line number 25 where the error is indicated.

3. 3

   Insert the declaration 'INT I' before the 'INI' line in the program, as this error often stems from the same missing variable declaration as error 2263.
