The print command can evaluate simple C/C++ expressions in the context of a stack frame. When a thread is suspended (see “Working with threads” above) just type:
[zxdb] print i 34
Expressions can use most simple C/C++ syntax:
[zxdb] print &foo->bar[baz] (const MyStruct*) 0x59f4e1268f70
You can also evaluate expressions in the context of other stack frames without switching to them (see “Interaction model” above for more):
[zxdb] frame 2 print argv[0] "/bin/cowsay"
Often you will want to see all local variables:
[zxdb] locals argc = 1 argv = (const char* const*) 0x59999ec02dc0
You can also set variables:
[zxdb] print done_flag = true true [zddb] print i = 56 56
