Restriction: This
is supported on AIX and Solaris.
When a process calls exec(), a new program is loaded to replace the current program.
The debugger suspends program execution at this point and opens a dialog, which allows you to choose whether to debug program initialization or whether to use a program profile. The name of the new program is shown, but, you cannot change the name. After you select OK, the debugger stops at the first instruction of the new program's runtime (if you asked to debug program initialization), or at the first instruction or statement in the new program.
