Thanks a million as always, Nick, very useful -longshape- of yours, too . PS-While matters are solved now, just to share my hazy idea- I thought of a possibility to use the -ds- in a loop (given that the labels were limited in no.) + reshape and making use of the fact that the variable names are stored in r()...but anyway its immaterial now. Thanks a lot indeed!
