Appendix A - Error Messages

The Full Screen Editor prints any errors it detects on the command line and pauses for you to type a carriage return to clear the error.

out of memory
The Editor was unable to allocate space to replace an existing line or add a new line.
unknown command
The editor encountered an unknown major command or subcommand character.
invalid pattern specification
A pattern was specified which was not acceptable because:
buffer has been modified, use qq to quit without saving
An attempt to leave the editor via the quit command when your text buffer has been modified since your last write to a file.
invalid line number or line range
A command has detected an invalid line number or range of line numbers. This can be caused by:
x command encountered within an execute file
An attempt has been made to nest execute commands.
current file not defined
An e,r,w or x command was entered without a filename and no current filename was defined. You can define it with the f command.
unable to access file
The file system was unable to open the requested file. This can be caused by:
syntax error
A recognized command was specified incorrectly. Some commands which do not take a line range will flag a syntax error if given one (e.g.: e, f).
filename too long
A pathname of more than 64 characters was specified on a e,f,r,w or x command.

Note: The QNX maximum pathname size is 255 characters, however the editor will accept only pathnames up to 64 characters in length. You may have to cd to a directory first in order to edit some files.

unknown option
An unknown option character was specified in the option command.
line greater than 512 chars
On a read from a file, a line greater than 512 characters was encountered. The line is broken at 512 characters. Reading will continue when you type carriage return. The j and s commands can also cause this error.
pattern not found
The pattern specified in a line search or a substitute command was not found anywhere in the buffer.
disk error
An error has occurred while trying to read/write a disk file. Make sure that the disk is not write protected (if writing). Otherwise, this error may signal a defective diskette or a bad block.
Attempt to write to a file which is not the current file. Use ww to force.
You are trying to write to a named file which is different from the one you edited. Perhaps you wanted to type "e file" and missed the "e" and hit the "w" instead. If you are sure, recall the line using the F10 key and insert a second "w" for a command of "ww file".
