Variables

Is there any way to tell how many things a variable is storing?

A variable stores 1 thing.
Such as 1 number, 1 string, 1 list, 1 database record. Perhaps you are looking to find out how many items are in that one list? That would be %numitems. You might also want to know how many digits are in that one number: %len(%string(@NumericVariable)). Could it possibly be that you seek to know how many words are in that 1 string? That would be %numwords. If it the number of values in that 1 db record then your going to have to ask someone else. |

Syntax: %numkeys(rec)
returns the number of keys in a database record

Also, Is there a way to create a temporary variable for just that alias?

What I do is just toss it out when I'm done...
#VAR myvar
<insert code here>
#UNVAR myvar
There may be a more proper way, but it works.

Yup, what dracx said. There are no temporary variables, but you can create it and the #UNVAR it. I usually also add a #GAG after #UNVAR so I don't have to see the message that the variable was deleted.
