I'd like to be able to read through data files, and be able to reject malformed

I'm assuming that to do this in SDL, I will have to read in _everything_ as a
string first, and then decide what to do with the information in that string
based upon its content.

Has anyone worked out macros to deal with strings such as left() mid() right()
Upper/Caps(), Lower(), Val[ue](), etc?

hexidecimal conversion? (to decimal)

Apparently there are macros to synthesize strings, but not analyze them.

Of course I find most of the string functions I was looking for AFTER I asked.
(the docs are hard to navigate/search sometimes - esp online, and the string
functions are split up into different sections)


substr()  [ mid() ]
strupr()  [ Upper/Caps() ]
strlwr()  [ Lower() ]
val()     [ Val[ue]() ]


and alignment macros in shapes.inc
