I use EpiData3.01 because I have used to the qes/chk/rec model. Now I encountered a strange problem as follow:My problem: In my project there are a series of y/n variables (0: no 1: yes 9:unkown) with default value 0. When I enter default 0 for about 40 times the EpiData goes funny.Qes and chk files are attached(I deleted rec file because the message with rec file was rejected yesterday). The error message after entering 40 of 0 for y/n variable:Access violation at address 00000000. Read of address 00000000.Many thanks and best wishes!hshxue@aliyun.com22:28 2013/7/23
