Arguments
expression
An argument to pass by descriptor. (a or n)
Discussion
^DESCR passes an argument by descriptor.
The result of expression is passed by descriptor. A descriptor is a memory block that contains information about the associated variable or literal.
Because Synergy DBL passes arguments by descriptor by default, ^DESCR is available only for consistency with the other methods of passing arguments (^VAL, ^REF, and ^XTRNL).
