Re: character ascii 127

Hello,

What language are you programming in and for what OS?

If you're using BASIC, the ASCII value 127 cannot be printed (see Microsoft article Q35651).

Another article that might help you is Q75857. Both of those articles can be found in the Microsoft or HP technical knowledge base.

Best regards,

Re: character ascii 127

The DEL character (as are the first 32 characters) is a terminal control character and as such is a non-printing character. The behaviour of this character depends on the "terminal". In other words it may display or otherwise depending on wether it is a word processor (and which variety) dos box, terminal or telnet session, gui display (depending on the dll) printer (which variety - different printers have different results).

The critical question is why do you want it to print?

Re: character ascii 127

Hello again,

My OS is unix. I print bar codes under a printer Lexmark with the language PCL. So that my bar codes is readable, it is necessary that I calculate and print a control's key. It worked very well until day my control's key corresponded to the character ascii 127.

Thanks for your help.
