The action of DIMing the variable makes its value NULL(Is that right?)

If I pass a parameter like I did above, does the script consider it dimmed?

If not how do I DIM it without losing its contents?

Break On

$= SetOption("Explicit", "On")

?"value=" $somevariable

Exit 0

When you enable the Explicit option, you must explicitly declare all variables using Dim, Global or ReDim statements. If you attempt to use an undeclared variable name, an error occurs. Use the Explicit option to avoid incorrectly typing the name of an existing variable.

function($var1,$var2)
  dim $var1,$var2
;...
endfunction

If Not IsDeclared($CL_ARG)		; is usually passed, but must be declared if not passed
  Global $CL_ARG
  ; can define default value here
EndIf

hmmm...
glenn, doesn't your code actually force kixtart to end processing if not declared?
you can't test $CL_ARG as explicit says you haven't declared it and bombs out.

Did you try it? I guess not

I use the same trick.

IsDeclared() has special processing which means that the script does not abort if the variable is undeclared. Just as importantly, checking if the variable exists does not create it implicitly.
