* Changed the way that Atmos programs are started. - Put a BASIC-language stub at the beginning. - Removed the Autostart flag. Those changes make it easy to give command-line arguments to a program. * Made the Atmos configure file accept a special symbol definition on ld65's command line. We can use "__RAMEND__" to increase the amount of RAM that's available to programs. 2014-11-09 11:32:11 +00:00			`__TAPEHDR__: type = import;`

Adjusted constructors. The constructors are _NOT_ allowed anymore to access the BSS. Rather they must use the DATA segment or the INIT segment. The latter isn't cleared at any point so the constructors may use it to expose values to the main program. However they must make sure to always write the values as they are not pre-initialized. 2016-03-16 15:28:32 +00:00			`ZP: file = "", define = yes, start = $00E2, size = $001A;`

Added the new INIT segment to all configs and adjusted formatting. git-svn-id: svn://svn.cc65.org/cc65/trunk@3402 b7a2c559-68d2-44c3-8de9-860c34a00d81 2005-02-25 07:52:50 +00:00			`TAPEHDR: load = TAPEHDR, type = ro;`

Renamed RAM to MAIN for all disk based targets. The name RAM doesn't make much sense in general for a memeory area because i.e. the zero page is for sure RAM but is not part of the memory area named RAM. For disk based targets it makes sense to put the disk file more into focus and here MAIN means the main part of the file - in contrast to some header. Only for ROM based targets the name RAM is kept as it makes sense to focus on the difference between RAM and ROM. 2016-03-07 00:28:55 +00:00			`STARTUP: load = MAIN, type = ro;`

Just some beautification. git-svn-id: svn://svn.cc65.org/cc65/trunk@5984 b7a2c559-68d2-44c3-8de9-860c34a00d81 2013-02-12 20:55:19 +00:00			`CONDES: type = constructor,`

Renamed INITBSS to INIT and INIT to ONCE. The way we want to use the INITBSS segment - and especially the fact that it won't have the type bss on all ROM based targets - means that the name INITBSS is misleading. After all INIT is the best name from my perspective as it serves several purposes and therefore needs a rather generic name. Unfortunately this means that the current INIT segment needs to be renamed too. Looking for a short (ideally 4 letter) name I came up with ONCE as it contains all code (and data) accessed only once during initialization. 2016-03-06 20:26:22 +00:00			`segment = ONCE;`
