BASIC and uppercase

Show all headers | View raw

I have been working with !Confix and have found that the
example uses a function to convert variable names to
uppercase before they are used in a CASE OF structure.

DEFFNupcase(input$)
   LOCAL pos%
   $par% = input$
   FOR pos%=0 TO LEN(input$)-1
      char% = ?(par%+pos%)
      IF char%>64 THEN
         ?(par%+pos%) = char% AND NOT 32
      ENDIF
   NEXT
=$par%

With the example,  
DIM par% 255 is needed but not included.

Two questions.
I am using the WHEN variables in mixed case, ie.

WHEN "Foo"  : Bar% = VAL(val$)
 
and no problems on my Iyonix.
Do earlier BASIC's need uppercase or is it some sort of
optimisation for BASIC to use uppercase?

WHEN "FOO"  : Bar% = VAL(val$) 

Secondly, for another purpose, the $ indirection is 
limited to 256 chars.
Would Martin's longstring library change this limit?

Thanks,  Ron M.
