Question on Discharge Papers

I asked my wife what her grandfather did in WWII. She had no clue, nor did his childern. I order the discharge papers and now I'm attempting to understand them.  He was discharged in September 1944 at the seperation center at Fort Sheridan, IL. He was a Private, Flight Traffic Clerk. Attended Ground School Div, Sta#11, PW, ATC Hamilton Fld, Cal; Grad. He was in the 1503 AAF Base Unit, PD, ATC. He has an honorable discharge
 
The comments on his seperation papers reads:
Physical Condition when Discharged: Good
Honorably Discharge by reason of: Sec X AR 615-360 & AAF Ltr 35-106, 28 Jun 44 & Ago **
Character: Excellent
Periods of Active Duty: 15 November 1943 - 16 September 1944
Remarks: **26 Jul 44, AG 220.8, 17 Jul 44 (OD-F-AAF-M). Convenience of the Government. No time lost under AW 107. Lapel Button Issued. Foreign Service: 14 days. Left United States 11 Aug 44; arr United States 22 Aug 44, mustering-out payment $100.00; entitles to $300.00
 
What does that mean? I cannot find a description of section X means, nor can I find a copy of the other guidence listed in the discharge. Nothing from what I've heard about the guy leads me to believe he had some sort of "issue" from the war, he was a sucessful businessman and on the board of his hospital.
 
Any help would be greatly appericated
 
Thanks,

Sta#11,PW,ATC is Station 11, Pacific Wing, Air Transport Command, which was active from about Oct 1943 until it was replaced on 1 Aug 1944 by the 1503rd AAF Base Unit (Port of Aerial Embarkation).  At the same time the Pacific Wing was upgraded to become the Pacific Division of Air Transport Command.  Both these units were at Hamilton Fld, Novato CA (just north of the Golden Gate on the bay side of the Marin Peninsula).
Ago is the Adjutant General's Office and AG is the Adjutant General (administrative offices og the Army)
AW 107 is Article 107 of the Articles of War.  No time lost means he did not lose any service time as a result of punishment for violations of the Articles.
AR 615-360 refers to an Army Regulation (presumably governing discharges).  I don't know what Section X is, I've only heard of Section VII.  Maybe one of the posters who served at the time can help with this.

He was an uninjured, honorably discharged veteran of a foreign war.  He only served a little less than a year on active duty.  He was discharged early for the convenience of the government, because the war ended and he was no longer needed.  He went overseas for a couple weeks, but he was not needed due to the end of the war.  He was not wounded and not entitled to service connected disability.  He was honorably discharged.  He was not a trouble maker and did not have to make up any bad time. If he had served time in the brig, he would have had an equal amount of time added to his enlistment.   He got his discharge pin...his 'ruptured duck'.  He was paid a $100 bonus and they owed him $300 in pay.  (If he had bad time he either would have had to make up the time or they would have deducted a certain amount per day from the amount he was owed. )  His amount owed would have included pay, and any leave days he had coming to him. All the rest is the regulations that authorize the Army to discharge him early.
