...]

Introduction
The CALL command executes a specified
logic block. Arguments can be passed and return values can be retrieved.
Arguments
ret_value
|
Value returned by the RETURN
command of the called logic. If more than 1 value is returned,
the keyword RETURNING must be used to assign data references
to the returned values. When only 1 value is returned, the
keyword RETURNING is optional. The returned value can in that
situation also be retrieved as a resultant of the logic in
combination with the LET command.
If no values are returned, the keyword RETURNING must be omitted.
|
logic_name
|
Contains the name of the logic block. This can either be a string
or a data reference.
|
logic_argument
|
Value which can be passed into a logic block. The command
PARAMETER within that logic
block will assign the values to local variables.
