Sorry, I may have confused the issue as I pasted in the result from
the Event log...
The actual script code is:
make new alias file at folder appFolder to AIfold with
properties {name:AI_ASName}
where the variables above are strings that are the paths to the two
places and the last one is the name of the new alias folder.
I never met difficulties with this syntax:
make new alias at folder "string:path:to:destination:folder:" to
("string:path:to:the:folder:to:alias:" as alias) with properties
{name:"mon_alias"}
"string:path:to:destination:folder:" may be replaced by a variable
of class string
or
folder "string:path:to:destination:folder:" may be replaced by a
variable of class alias.
"string:path:to:the:folder:to:alias:" may be replaced by a variable
of class string
or
("string:path:to:the:folder:to:alias:" as alias) may be replaced by a
variable of class alias.
