loops

I have an each method that is run on some user-submitted data.

Sometimes it will be an array, other times it won't be.

Example submission:

<numbers>
    <number>12345</number>
</numbers>

Another example:

<numbers>
    <number>12345</number>
    <number>09876</number>
</numbers>

I have been trying to do an each do on that, but when there is only one number I get a TypeError (Symbol as array index) error.

RETURN END Which is called in another subroutine by: CALL SSUB(W(0,1,0,1),...) where W is a 'working array'. It appears that a specific… >>> More
