delete(var) and try-catch

Hello,

Is there any way to turn the following into
a procedure ?

if( isvar("foo") )then
  delete(foo)
end if

Related to this, is there any way to perform
a "try-catch" statement in order to try executing
a statement and catching any errors so that the
script does not exit on a failure ? For example,

begin
  print(1)
  delete(myvar)
  print(2)
end

will never get to "print(2)" if "myvar" does
not exist (using delete() as an example of
something that could fail).

Something like

try:
  delete(myvar)
catch IERR:
  print("no myvar, error code "+IERR)
endtry

Thanks, Bruce
