close(writefile)

new topic     » topic index » view thread      » older message » newer message


So i have writefile open, and i am writing, and the debugger says writefile equals 4, and now i want to close it. So i close(writefile). The debugger says writefile is still 4. I cannot test the variable writefile in any way for being open or closed or an error. At best, i can write code to make it a sequence and subsequently test for it's lack of atom-ness.

Can we have close(writefile) change the handle writefile to zero, please?
