* In [[SHARP APL]] and [[J]] stranding is called '''vector notation''' and is a part of token formation rather than execution. Only plain numbers are stranded. | * In [[APL\360]], [[SHARP APL]] and [[J]] stranding is called '''vector notation''' and is a part of token formation rather than execution.

An example in which stranding interferes with the most obvious way of writing a program is shown below. Consider applying the function <source lang=apl inline>f</source> to <source lang=apl inline>0.8</source> three times using the [[Power operator]]: | An example in which stranding interferes with the most obvious way of writing a program is shown below.
