A integer-type constant is expressed as a decimal number or a hexadecimal number which begins with a "$" character. Floating point operation is not supported.
Example: 123 -11 $3a $10F
Note on negative integer constants
There are two ways of expressing a string-type constant.
a) A character string quoted by ' or " (both sides must be same).
Example: 'Hello, world' "I can't do that"
b) A single character expressed as a "#" followed by an ASCII code (decimal or hexadecimal number). Note: Strings can not contain NUL (ASCII code 0) characters.
Example: #65 The character "A". #$41 The character "A". #13 The CR character.
ASCII code table
Format a) and b) can be combined in one expression.
Example: 'cat readme.txt'#13#10 'abc'#$0d#$0a'def'#$0d#$0a'ghi'
