I have a program in which I repetitively read in a string. According to what
the string contains, I do a variety of things - set up an option, display a
file, execute a system command, etc.
 
I would like to do this (fairly obviously) in a case statement, but the test I
am carrying out are so varied that I can't quite see how to fit them into a
case statement, for example, I will be doing:
 
if match("!",string) then...
if match(";",string) then...
if find("*",string) then...
if type(string) == "integer" then...
...some default action...
 
Any ideas on how I may set this up in a case statement please? Note that
because a string starts with "!", this does not preclude the possibility of it
also including a "*" elsewhere, so I guess a series of simple if statements
won't do the job as in such a circumstance, 2 of the blocks of code would be
executed...
 
I guess that there is a ridiculously simple answer, but I don't see it yet!
 
Thanks.
