line break in formatted output

Hi

this code

write(CSTmp,"(I0)") size(this%RVPEffSize)
CSFormat="("//Trim(AdjustL(CSTmp))//"(1X,F20.10))"
write(this%ISOutputUnitEff,CSFormat,iostat=ISSubStat,iomsg=CSMsg)&&(this%RVPEffSize(c1),c1=1,size(this%RVPEffSize))

is supposed to write the content of "this%RVPEffSize" into a single line of the file. It does so until "size(this%RVPEffSize)" is 51422. For larger sizes, a new line is inserted.

Is that intended or a bug or related to the operation system???

Thanks

Karl
