"Expecting or or ... before ''"
Enter a valid operand at the named position.
"Expecting ':=' or '=>' before ''"

"'INI' operator needs function block instance or data unit type instance"
Check the data type of the variable, for which the INI operator is used.
"Nested calls of the same function are not possible."
At not reentrant target systems and in simulation mode a function call may not contain a call of itself
as a parameter.
Example: fun1(a,fun1(b,c,d),e);
Use a intermediate table.
"Expressions and constants are not allowed as operands of 'ADR'"
Replace the constant or the expression by a variable or a direct address.
"'ADR' is not allowed on bits! Use 'BITADR' instead."
Use BITADR. Please Note:
The BITADR function does not return a physical memory address.
"’’ operands are too few for ''. At least ‘’ are needed"
Check how many operands the named operator requires and add the missing operands.
"’’ operands are too many for ''. At least ‘’ are needed"
Check how many operands the named operator requires and remove the surplus operands.
