The clearselect statement clears the active select-list specified by the list.var and releases all overflow associated with that list. Any external select-list is also cleared if the list variable is not specified.
clearselect {list.var}
Example 1
5 *
readnext key else
print ’Frist Week ’,hours
stop
end
read member from file,key else goto 5
hours += member<4>
print member<1>,member<4>
if hours > 40 then
clearselect
goto 5
end
Example 2
This example shows how to un-assign a variable to clear memory so that the memory can be used for something else:
Type:
a = 5 print a clearselect a print a
Output after compiling:
5 [B10] in program “p21”, Line 4: Variable has not been assigned a value; zero used. 0
The variable is now available for you to use.
