I'm writing a code resource using think C 3.0. I want to be able to pass a string constant to a function like this: call_function ("this is a string"); I disassembled and looked closely. When I do the above, think C stores the string in global area and accesses it via the A4 register. So, unless I use the macros provided by Think to restore the A4 after each call, the above doesn't work since we all know globals are a no-no in code resources. I don't really want to use the macros since the string stuff isn't really necessary (used for debugging). My question is whether there is a simple way to have C tag the string after the subroutine that uses it, and have the string be accessed locally via the A6? --Ron Smith

Version 4.0 stores strings and globals in a PC-relative location for single-segment code resources, so RememberA0/SetupA4/RestoreA4 are no longer necessary.
