No you do not need to declare an array in this case. It is not actually an array; it is just called "array notation" because it is the same syntax you would use on an array. FORM is actually a predefined structure/collection (aka 'scope')... such as URL or VARIABLES scopes
Most variables that you can reference as scope.variable, you can reference as scope[variable] In your last example: <cfset LegalProteinSequence_#LoopCount# = ... You are right, that does not work. You can do one of the following instead: <cfset "LegalProteinSequence_#LoopCount#" = ... <cfset variables["LegalProteinSequence_#LoopCount#"] = ... <cfset variables["LegalProteinSequence_" & LoopCount] = ... .:.:.:.:.:.:.:.:.:.:.:.:.:.
