## 6.5.3 Spaces

| Search internet |

The lgs language is 'space sensitive'. If you write

((2,3))

or

( ( 2 , 3 ) )

then lgc will not understand you. The combinations construct has form

(( " , " ))

Thus, you must write

(( 2 , 3 ))

with spaces around 2 and 3 and no spaces between parentheses.

An arbitrary sequence of space and newline characters count as a single space so you can also write

(( 2 ,
3
))
