Question : Powershell: How can I run a program with a parameter list that is stored in a variable?

I want to run a program with a specific parameter list from the Powershell prompt. If I run it directly it works just fine.
./myScript.ps1 myParam
If I store the filename in a string it works as well:
$myString = "./myScript.ps1"
&$myString
But if I add the parameter to the string I can't make it work:
$myString = "./myScript.ps1 myParam"
&$myString

Instead, the prompt returns:
The term './myScript.ps1 myParam' is not recognized as a cmdlet, function, operable program, or script file. Verify the term and try again.

What is the best way to do this?

in this case you need to use invoke-expression

$myString = "./myScript.ps1 myParam"
invoke-expression $myString

& Assumes the entire string is one command.
