Hallo Karsten,

   another possible solution is the format option for the string
function, see example below.

Cheers,
Martin

; generate two example strings of 300 byte length each
b=bytarr(300)+65B
c=bytarr(300)+69B
bs=string(b)
help,bs
; BS              STRING    =
'AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA'...
print,strlen(bs)
;         300
cs=string(c)

; if you use only the string function, IDL will generate a string array
ds=string(bs,cs)
help,ds  & print,strlen(ds)
; DS              STRING    = Array[2]
;        300         300

; however, if you add the format option, you can concetanate the strings
ds=string(bs,cs,format='(A,A)')
help,ds  & print,strlen(ds)
; DS              STRING    =
'AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA'...
;        
600
