Need help on this. I need to increment a variable by 1 but retain as 2 characters.
I am using expr to do additions:
$SERIAL can range from 01-99. After adding "1", I need the result to be 2 characters, eg: 02+1 = 03. By default expr will truncate the zero such that 02+1 will become "3" not "03"
Please help. Much appreciated.
Thanks.

Hello,
I'm trying to write a while loop for a decimal value in tcsh which I know can't be done. Instead I want my increments to be one order of magnitude too large and then divide it by 10 when I use the variable. However, I don't know how to divide my variable and set it as another.

The code below extracts the pixel value at position X Y. The... (3 Replies)
