Hello,
@George: the output_cmd and input_cmd seems to be correct to me. the structure
comes in with positions, which is declared as __structure.
@Charlie: The script is once executed as a test without any parameters given.
This gives you the error because you dont have an object in "positions".
lso you can't manipulate input parameter (input_cmd = ''"; will fail).
When I read your code correctly, you want to push through the input_cmd to
output_cmd only if there is an object in the structure. (anyways, I am not sure
about testing against "null" here)
function (__string output_cmd) main (__string input_cmd, __structure positions)
{
var output_cmd = "";
if (Object.firstRun == undefined) {
Object.firstRun = 1;
}
else{
if (positions[input_cmd] == null) {
output_cmd = "";
}
else{
output_cmd = input_cmd;
}
}
var result = new Object();
result.output_cmd = output_cmd;
return result;
}
I didn't test the code...
best,
