hello people this is not clear to me but i figure some of the IDL GURU's
can help me out i have an bsq file with the dimensions of 554*521*42 and
tried to use the ASSOC function since i knew the dimensions and so
created a structure :
2 variables of x=FLTARR(554) and y=FLTARR(521) and REPLICATED the
structure 42 times into a third variable and then tried the ASSOC
function with it and it ran fine except for when i tried to access any
data it would give me the error of
"File expression not allowed in this context: RESULT."
and if i peaked into it using the variable watch it would crash IDL
every time. Kinda makes me wish that anything in IDL work as it's
designed to.
I'm using IDL 5.2
PRO Profiles
;dealing with a 3D array of sorts.
z= 42 ;depth of the array
data={mo,x:FLTARR(554),y:FLTARR(521)}
data_cube=REPLICATE(data,z) ;this is to hold the bsq ;file
help,data_cube
help,data

filepath=DIALOG_PICKFILE(/MUST_EXIST,TITLE='SELECT DATA FILE')
GET_LUN,unit
OPENR,unit,filepath
result=ASSOC(unit,data_cube)
;READU,unit,data_cube,TRANSFER_COUNT=count
CLOSE,unit
FREE_LUN,unit

a=result(0).y[0:6]
print,a
print,result.(0).x[*]
