Reading large Ascii files [message #27641]

Hello,

I am trying to read a single row from a large file. The amout of numbers per
row is about 12500. So in IDL i have the following lines;

readf,lun,format='(500F8.3)',ch1_val_s

so that i only read 500 values at a time and it gives me the error;

% Input line is too long for input buffer of 32767 characters.

From what i can gather, IDL is trying to read the whole line first before it
puts it into the array. Can anybody suggest a way round this please.

Thanks

Isa Usman
