The $prv_rd variable stores backend sqlite data (varchar data type). The data is 0000874. In order to perform any mathematical operation on this data, I use :
set calc [expr $prv_rd+2] The above expression gives me the following error message : Error : expected integer but got "0000874" ( looks like invalid octal number ) How do I get rid of this error? Any early help will be appreciated. Thanks. Anirban Sarkar
