add Attribute using a loop

[NaughtyNathan]

string $animControl[] = "curve1_ctrl";
setAttr -e-keyable true ($animControl[0] +" .$ctrlAt");



putting [] after a variable name declares it as an array. You cannot assign a single string as an array like this. What are you trying to do? should $animControl be an array? or a single string?

also, you've put a variable INSIDE a literal string: ($animControl[0] +" .$ctrlAt") should be:
($animControl[0] + "." + $ctrlAt);

variables shouldn't ever be inside quotes (unless you're doing really clever/complex code), and finally, don't put spaces inside your object/attribute concatenations (" ." above)


// array method:
string $animControl[] = { "curve1_ctrl" };
setAttr -e-keyable true ($animControl[0] + "." + $ctrlAt);

is fine, or:

// single string method:
string $animControl = "curve1_ctrl";
setAttr -e-keyable true ($animControl + "." + $ctrlAt);

but not what you've got.
