of "X1=4+5" are not recognized.
• The system recognizes hexadecimal constants in the form of X1='HFFFF',
binary constants in the form of X1='B10010' and exponential components in the
form of X1='-.5EX-4'.
Note
The value of a string can be output if it contains the following between string and
value:
• Nothing
• Space character
• Equality sign
