请问write怎么把输出数据排到一行？

lxs123

'reinit'
'sdfopen F:\grapes_gz3km_nc\z1.nc'
file="f:\output\grapes_gz.txt"
'set lat 28'
'set lon 112'

'set gxout print'
*'set prnopts %1 10 1'
'd ugrd_1000mb'
record=subwrd(result,10)
rc=write(file,record,append)

*'set gxout print'
'd hgt_850mb'
record=subwrd(result,10)
rc=write(file,record,append)

*'set gxout print'
'd  rh_2mabovegroun'
record=subwrd(result,10)
rc=write(file,record,append)

rc=close(file)
'quit'
;


以上脚本输出是：
3.36346
1486.75
88.5009


现在我想让它这样输出：
3.36346 1486.75 88.5009

请问要怎么修改？
