You may recognise the pattern here as [[wikipedia:augmented assignment|augmented assignment]] from C and related programming languages. APL allows you to use any function to modify values in-place. If you are not familiar with this, then just think of <source lang=apl inline>name,←value</source> as <source lang=apl inline>name←name,value</source> (but the pass-though value is whatever is on the right of the assignment arrow). | You may recognise the pattern here as [[wikipedia:augmented assignment|augmented assignment]] from C and related programming languages.
