Let me quote the course document I am now reading..
"Because this field is of no use for the end user we make it also invisible"
"Modify again the prompts .."
"Leave a blank column .. so you can insert later the workfield .."
"While testing .. you will remark that there is no .. yet .."
"Enter now in the .. the command .."
And this is from 3 random pages!! This sounds like Babelfish translation, yet I know its human translated.. Its incredibly sad :s And hugely distracting!
