Examine the error message; it indicates an invalid column name in line 1 of the query. Instead of re-entering the entire command, you can correct the mistake by editing the command in the buffer. The line containing the error is now the current line.
This command has three parts, separated by slashes or any other non-alphanumeric character:. The CHANGE command finds the first occurrence in the current line of the character sequence to be changed and changes it to the new sequence. Re-enter the line by typing the line number followed by a space and the new text and pressing Return. Now that you have corrected the error, you can use the RUN command to run the command again:.
To insert a line before line 1, enter a zero "0" and follow the zero with text. Press Return again to indicate that you will not enter any more lines, and then use RUN to verify and re-run the query. To append a space and the clause DESC to line 4 of the current query, first list line Type RUN to verify the query:.

You can have many commands in the file. To run a series of scripts in sequence, first create a script containing several START commands, each followed by the name of a script in the sequence.
The command may be useful in this example. See the EXIT command in this chapter for further information. If your script generates a SQL error while running from a batch file on the host operating system, you may want to abort the script and exit with a return code.
Note that you can also define user variables to use in titles and to save your keystrokes by defining a long string as the value for a variable with a short name. You can enter any string at the prompt, even one containing blanks and punctuation. If the SQL command containing the reference should have quote marks around the variable and you do not include them there, the user must include the quotes when prompted.
You should avoid creating substitution variables with names that may be identical to values that you will pass to them, as unexpected results can occur. If a value supplied for a substitution variable matches a variable name, then the contents of the matching variable are used instead of the supplied value.

This is especially useful for storing complex commands or frequently used reports. Your operating system may have one or more text editors that you can use to write scripts. For example, to define the editor used by EDIT to be vi, enter the following command:. To create a script with a text editor, enter EDIT followed by the name of the file to edit or create, for example:. EDIT adds the filename extension.
