Hey Tony,
The string format in blitz 2.1 seems to be
-8 BufferLen.l - Length of the allocated space for string to grow
-4 StringLen.l - Actual Length of string
0 Data - String Length Bytes
(StringLen) PAD.b - Zero end of string
Note: if BufferLen=StringLen and is even (ie / 2) then pad is .w, as
allocated
memory is always even
On top of that you have the allocmem data (-12 is size of allocated memory
for whole structure, -16 is next item in the mem list) in a normally
allocated string.
You could fix a string into a dc statment, and then do something like
*Something.s=?MyString
But I have a feeling blitz does not let you use pointers with it`s basic
types.
Not sure that helps but you could write a machine code routine to point a
real blitz string at your static one, bit messy but I don`t see why it
wouldn`t work.
Good luck,
Dave
