Symptoms:

ioControl OptoScript may allow assignment of an unquoted hexadecimal sequence of characters to a string variable and cause ioControl to close out when the Test Compile or the OK button is pressed. OptoScript should not allow assignment of a number to a string variable.

Examples:
This string assignment makes ioControl close out:
    myString =
    000004100000FFFFF0D83002003C0000546869732077696C6C2074657374205443
    502062792077726974696E6720746F2073637261746368207061642052414D2076696120
    5443502E000000;
The following string assignments result in the expected compile error:
    myString = 696C6C2074657374205443502062792077726974696;
    myString = FFFFF0D84696;
