Hello.. is it possible to append some data on a text output file appending the data to each row, and without use too much computational I/O ??
Instead of the classical way:
VARX VARY VARZ... year1 x1 y1 z1 year2 x2 y2 z2
.. I would like to use the much more redeable:
year1 year2 .. VARX x1 x2 ... VARY y1 y2 ... VARZ z1 z2 ... ...
where the 1,2 series are wroted on different times.. a sort of a appendByRow() function.. and I would avoid of load the whole file in memory and then printing it line-by-line..
is it possible ??
