1207 sys$sigprc for one of two reasons:
1209 1.) If the kill() in an older CRTL uses sys$forcex, causing the
1210 target process to do a sys$exit, which usually can't be handled
1211 gracefully...certainly not by Perl and the %SIG{} mechanism.
1213 2.) If the kill() in the CRTL can't be called from a signal
1214 handler without disappearing into the ether, i.e., the signal
1215 it purportedly sends is never trapped. Still true as of VMS 7.3.
1217 sys$sigprc has the same parameters as sys$forcex, but throws an exception
1218 in the target process rather than calling sys$exit.
1220 Note that distinguishing SIGSEGV from SIGBUS requires an extra arg
1221 on the ACCVIO condition, which sys$sigprc (and sys$forcex) don't
1222 provide. On VMS 7.0+ this is taken care of by doing sys$sigprc
1223 with condition codes C$_SIG0+nsig*8, catching the exception on the
1224 target process and resignaling with appropriate arguments.
1226 But we don't have that VMS 7.0+ exception handler, so if you
1227 Perl_my_kill(.., SIGSEGV) it will show up as a SIGBUS. Oh well.
1229 Also note that SIGTERM is listed in the docs as being "unimplemented",
1230 yet always seems to be signaled with a VMS condition code of 4 (and
1231 correctly handled for that code). So we hardwire it in.
1233 Unlike the VMS 7.0+ CRTL kill() function, we actually check the signal
1234 number to see if it's valid. So Perl_my_kill(pid,0) returns -1 rather
1235 than signalling with an unrecognized (and unhandled by CRTL) code.

3982 * command execution '&'. All of these capabilities are provided to any
