In addition to Bo's comment, you could build your function to take a
refinement if that seems less cumbersome in your common use.
Assign: Func [
"Creates an Amiga-like Assign command."
Volume [ Word!] "The function that this commmand will create."
Path [ String! File! ] "The path that will be assigned to it."
] [
Do Rejoin [
Volume
": Func [/with AssignPath] [to-file Join %"
Path
{ either with [AssignPath][""] ] }
]
]
Then you would use it like this:
read REBSOURCE
do REBSOURCE/with %hello.r
