Message line

The sixth screen line is known as the message line. It may contain error messages, help information, instructions or suggestions for the user at various points in the program.

When a tableBASE call returns an error status, TBERROR appears at the left of the message line. Errors detected in the DK1TDRVC conversion routines cause ERROR to appear at the left of the message line. If DK1TDRVC is in HELP or FORMAT mode (see Ruler line), an error message will appear on the right side of the message line. Error codes for tableBASE errors appear in the “ERR” and “ERRSUBCD” fields on the command line, while messages for those errors appear on the message line.
