Narrative:
Original clearance from pre departure clearance was the texoma departure to tul with a revised segment of the acuna departure to mcalester. It seems that tower suspends RNAV departures and issues headings after takeoff any time there are thunderstorms anywhere in the state of texas. There were storms east of dfw; so I assumed that was why we were given the texoma departure instead of an RNAV departure. Note that the transition was also changed. I assumed this was for WX also. I had missed the fact that the whole type of departure was revised (from texoma to acuna RNAV); mistakenly thinking only the transition of the texoma departure was changed. I think this was a misuse of the revised segment portion of the ACARS pre departure clearance program. This was not just a revision of a segment of the departure; it was a complete change in the type of departure. It would have been better if ATC had sent a message on the pre departure clearance to call them for a full route clearance.

Title: MD80 FLT CREW DEPARTING DFW RECEIVES REVISED SEGMENT PDC; AND FAILS TO NOTE ENTIRE SID HAS BEEN CHANGED; NOT JUST TRANSITION.
Narrative: ORIGINAL CLRNC FROM PDC WAS THE TEXOMA DEP TO TUL WITH A REVISED SEGMENT OF THE ACUNA DEP TO MCALESTER. IT SEEMS THAT TOWER SUSPENDS RNAV DEPS AND ISSUES HEADINGS AFTER TAKEOFF ANY TIME THERE ARE THUNDERSTORMS ANYWHERE IN THE STATE OF TEXAS. THERE WERE STORMS E OF DFW; SO I ASSUMED THAT WAS WHY WE WERE GIVEN THE TEXOMA DEP INSTEAD OF AN RNAV DEP. NOTE THAT THE TRANSITION WAS ALSO CHANGED. I ASSUMED THIS WAS FOR WX ALSO. I HAD MISSED THE FACT THAT THE WHOLE TYPE OF DEP WAS REVISED (FROM TEXOMA TO ACUNA RNAV); MISTAKENLY THINKING ONLY THE TRANSITION OF THE TEXOMA DEP WAS CHANGED. I THINK THIS WAS A MISUSE OF THE REVISED SEGMENT PORTION OF THE ACARS PDC PROGRAM. THIS WAS NOT JUST A REVISION OF A SEGMENT OF THE DEP; IT WAS A COMPLETE CHANGE IN THE TYPE OF DEP. IT WOULD HAVE BEEN BETTER IF ATC HAD SENT A MSG ON THE PDC TO CALL THEM FOR A FULL RTE CLRNC.
