Errors That Can Occur With Expressions
Some of the error messages that occur when using expressions need no further
explanation:
Missing left parenthesis
Missing right parenthesis
Variable name expected
Number expected
Floating point numbers limited to 5 digits
Function expected
New line expected
Equal sign expected
Other errors are explained below.
Variable Name Expected
This message occurs when the expression is not set equal to an Input Location
label. The label must be to the left of the expression and not enclosed in
parentheses. An expression that contains no equal sign causes compiler error
202, “unrecognized text”.
For Example:
“Variable name expected” is displayed when a program contains any of these
expressions:
5=el*(Vee+en)
(lambda) = COS(theta)
10–(zee/2)=bee
These are correct ways of entering the above expressions:
five=el*(Vee+en)
lambda = COS(theta)
bee=10–(zee/2)
Number Expected
Indicates one of the following situations:
(1) An expression with a /, *, or ^ operator is missing a number or label
before and/or after the operator.
(2) An expression with a + or – operator does not have a number or label after
the operator.
(3) An expression with an @ operator does not have a number after the @;
only a fixed number is allowed immediately after the @ operator.
(4) An expression with an @ operator does not have either a number or label
before the @.
(5) There is nothing between a pair of parentheses (e.g., the expression
contains this “()”).
(6) A number is immediately followed by a label or function without an
operator (e.g., an expression containing “8label” gets this error message).
