Note: This article only applies to SCI Companion
Introduction
The "if" statement does not return a value, making a the nesting of if's (inline) like this not possible:
Code:
(if (> a ((if(> b c) 5)(else 9)) d) // This syntax works in SCI Studio, but will not compile in SCI Companion
...
)As indicated above, this code will work in Studio, but will not work in Companion. The way to handle this in Companion is to implement a procedure, which will return a value:
Code:
(procedure public (if pCondition pTrue pFalse)
(if (pCondition)
return pTrue
)(else
return pFalse
)
)The original statement can now be re-written as:
Code:
(if (> a iif(> b c 5 9) d)
...
)
