Hello,

We want to use LPC2148 for big project,So How much file size can be
supported by SCARM ?
& Hv u another option for bigger file size?

I'd never heard of SCARM until you posted this (you should have posted a
link).  It is not a GNU compiler, so you are on the wrong forum.
Moreover it is a commercial product, so you should get support from the
vendor. http://www.spjsystems.com/support.htm

I am nor sure what you mean by "file size", but I would be very
surprised is there were any code size limit with any compiler; the limit
of code size is determined by your hardware.

If you rather mean the limit of source file size, then you are wrong
thinking.  For large projects (in fact for any non-trivial project), you
should use separate compilation and linking of a number of smaller
modules rather than placing all your code into a single file!  Even then
I would be surprised if there were any limit other than that imposed by
the host Operating System - so no practical limit.
