Moves the current member pointer to the first member in a result set.
TOP [setname]
| setname | The name of a result set. If setname is omitted, the current set is used. |
The TOP command moves the current member pointer to the first record in the current set.
In a template program, indicates that the next line is to be joined to the current line at the output destination.
linestart «$ linecontinue »
where
| linestart | any portion, from the beginning, of an output line |
| linecontinue | the remaining portion(s) of the same output line |
In a template program, the dollar sign ($) indicates that the next line is to be joined to the current line at the output destination.
Normally, each physical line in a template is sent as a separate line to the current output destination. To cause successive physical lines in a template to be joined into one line in the output, end the appropriate lines in the template with the dollar sign ($).
If a line must end with a dollar sign for some other reason, ask the software to interpret the dollar sign by placing a backslash ( – Escape) preceding the dollar sign.

SET CURRENTSET setname
| setname | The name of an existing result set. |
Normally, the current set is the result set produced as a result of the last FIND command executed. SET CURRENTSET enables you to select another existing result set to use as the current set.
The SET CURRENTSET command takes effect immediately upon parsing or compilation, not just when the compiled program is executed.
The SET CURRENTSET command is not affected by the SET RESET and SET RESTORE commands.
procedure test3 (a,b)
if a = b
find Employees -> EmpSet
else
find Departments -> DeptSet
endif
if a = b
set currentset EmpSet
let a = LastName
endif
The SET CURRENTSET command ensures that the correct set is recognized as the current set.
