Writing memory with GDB.

Greetings.
Can I write memory locations with GDB? I have been looking through 
Debugging With GDB and a few tutorials but can't find anything - only 
how to read memory and write to variables. I am using GDB 5.1.1 for TI 
MSP430 in text mode but I expect the commands would be the same as for 
native debugging.
Help appreciated.

I'm pretty sure you can.  Even if it doesn't have a special command for
that, something like

	set *((unsigned char *) 0x1234567) = 50

at the command line should always work.

To some extent, that's understandable --- GDB is a source-level
debugger, mainly.  I.e. if some piece of memory isn't available as
some variable, then you shouldn't need to fiddle with it, because the
program has no (allowed) way of accessing that memory.
