I think this underscores the need for REAL type checking. I was told
that a positive integer would return true if "is a date" is used.
As easy as non-typed variables are, it often becomes necessary to
check for such things. I for one would like to be able to have the
option of having new global variables initialized with NULL or
UNDEFINED or something, so that I can check for the first time
initialization of said variables. Maybe there could be an addition to
the global/local variable declaration so that if you include an
arguement and the variable is undefined as of yet, it will initialize
the variable with your arguement as in:
global bobtest "NULL"
If bobtest already exists it will leave it as is, but if not it will
initialize it with the string "NULL" or whatever you tell it to.
<sigh> if only I ruled the world...
