Format codes problem [message #47566]

Hi

I have a problem with the format codes. I have to create filenames from two
index arrays. To do this I use the string command with format codes. If I
create the filename for each element of the index array step by step I get
the correct result if I do the operation for the entire array the result is
crap. The code looks like this:

IDL> gi=[1010,1007,1006,1011,1009]

IDL> gj=[509,510, 510,509,509]

IDL> for i=0, 4 do print, String(Format='("g",i4.4,i3.3)',gi[i],gj[i])
g1010509
g1007510
g1006510
g1011509
g1009509

IDL> print, String(Format='("g",i4.4,i3.3)',gi,gj)
g1010*** g1006*** g1009509 g0510510 g0509509

Does anyone know what is going on?
