Explicitly define a block of WebDNA code that has a separate variable space
numero = 235-Scope begin...[scope name=mytempvars][text]a=11[/text][text]b=22[/text][text]c=33[/text]List of local scope variables...Result...-Scope begin...List of local scope variables...a=11b=22c=33-Scope end...List of global variables outside scope...So you can see that the 'local' scope variables; 'a','b', 'c', only exist between the [scope] tags. This is useful when you need to create several temporary variables for a specific block of WebDNA code, but do not want the variables 'cluttering' the global template variable space.Scope and Functions:WebDNA functions have their own implied scope. Meaning that when you create variables inside of a function definition, the variables are local to that function. The 'name' of the variable space in the function, is the function name itself. For example...
[listvariables scope=mytempvars][name]=[value][/listvariables]-Scope end...[/scope]List of variables outside scope...[listvariables scope=mytempvars][name]=[value][/listvariables]
[function name=test_function][loop start=1&end=10][text]local_[index]=[index][/text][/loop][listvariables scope=test_function][name]=[value][/listvariables][/function][test_function]Results...local_1=1local_2=2local_3=3local_4=4local_5=5local_6=6local_7=7local_8=8local_9=9local_10=10By default, text variables created within a function are discarded after thefunction has finished. If you want to create a text variable within afunction that persists after the function completes, then you need toexplicitly set the variable scope to global. For example:
[function name=myfunction]put stuff in here and it won't show...[text scope=global]var1=foo[/text][text]var2=bar[/text][return]anything you want displayed[/return][/function][myfunction] produces [var1] and [var2]Result...anything you want displayed produces foo and [var2]Reserved Scope Names
There are a few 'reserved' scope names: "global" : Refers to the 'normal/secure' template variable space. "local" : When used inside of a function or scope context, refers to the variable space associated with the current function or scope. "insecure" : Refers to the 'insecure' template variable space (this space also includes HTML form variables).

[myfunction] produces [var1] and [var2]
There are a few 'reserved' scope names:
"global" : Refers to the 'normal/secure' template variable space.
"local" : When used inside of a function or scope context, refers to the variable space associated with the current function or scope.
"insecure" : Refers to the 'insecure' template variable space (this space also includes HTML form variables).
