^ARG(position)
Arguments
position
The ordinal position of the parameter. (n)
Discussion
^ARG accesses the specified formal parameter as alpha data type (a). It is equivalent to ^ARGA.
^ARG is a positional parameter reference and cannot be present in a main routine. In Synergy .NET, the specified parameter must be a descriptor type.
When ^ARG is used, the parameters do not have to be defined in the subroutine parameter block.
Using ^ARG* on declared arguments can cause high overhead. |
