Hi all, Let me use a simple example to ask my question. Lets say i have the following data showing hid (household identifier), and variable g1- g200 as follows: hid g1 g2 g3 g4 g5......................... 111 2 0 0 4 1............................. 112 0 0 1 3 2............................. 113 1 4 1 0 3............................ 114 0 0 1 2 2............................ ............ ....up to 30000 households How can I generate new variable(s) X1- X20 which contains the first 20 numbers ( excluding the zeros) from g1- g100?. For example: hid X1 X2 X3 ............................ 111 2 4 1 ............................. 112 1 3 2 ............................ 113 1 4 1 ............................. 114 1 2 2............................... ...... .... Thank you in advance for your assistance...
