What do you guys think of a good old fashioned case statement?
case: func [
"If condition block is true, evaluates subsequent block."
cases [block!] "Block alternating with conditions blocks and action
blocks"
/default
default-case [block!] "Default case if no others found."
] [
forskip cases 2 [
if do first cases [
return do first next cases
]
]
either default [ do default-case ][ none ]
]
a: 1
b: 2
c: 3
confirm case [
[ c = a ] [ probe "C = A" ]
[ a = b ] [ probe "A = B" ]
[ a = ( b + c ) ] [ probe "A = B + C" ]
[ c = ( a + b ) ] [ probe "C = A + B" ]
]
a: 11
b: 200
c: 32
confirm case/default [
[ c = a ] [ probe "C = A" ]
[ a = b ] [ probe "A = B" ]
[ a = ( b + c ) ] [ probe "A = B + C" ]
[ c = ( a + b ) ] [ probe "C = A + B" ]
] [ probe "default" ]
