How to combine following arrays in a single file?
A FLOAT = Array[195]
B FLOAT = Array[1440, 195]
C FLOAT = Array[195]
D LONG = Array[1440]

I didn't mean this. What i wanted to do is to make an array [195,1440] after combining these variables.

Impossible.
IDL> print,195+1440*195+195+1440
282630
IDL> print,196*1441
282436

The easiest way is to first make the output array
outarr = fltarr(1441,196)
and then add subarrays where you need them
outarr[0:1439,0:194] = findgen(1440,195)
outarr[1440,0:194] = findgen(195)
outarr[0:1439,195] = findgen(1440)
making the sure that the sizes of the arrays on the left and right hand side are the same. One of your subbarrays was integer while others were floating point. If you really want ot maintain this distinction when combining them then I suggest using the LIST() function.

if i understand correctly what you want, i see 2 possibilities:
outarr=[[[reform(A,[1,195]),B,reform(C,[1,195])]],[0,D,0]]
or using Wayne's approach
outarr = fltarr(1442,196)
outarr[0 ,0:194]=reform(A,[1,195])
outarr[1:1440,0:194]=B
outarr[1441 ,0:194]=reform(C,[1,195])
outarr[1:1440,195 ]=D
You could also use transpose instead of reform, but reform should be
faster. However reform only gives the same result as transpose if A and
C are vectors, i.e. if 2 dimensions have size >1 you have to use transpose.
