Warnings and Error Messages

Warning messages are displayed for information only. They tell you about any constraints on your use of PLOT or advise you of actions that PLOT has taken automatically.

All errors during PLOT's processing operations are fatal. When an error occurs, PLOT displays an appropriate error message on your command prompt window and then terminates its data processing.

Typical messages, and suggested responses, are as follows:

Error: Cannot create/open output file

Check that the named output file is valid, is not protected from access, and is not already in use.

Error: Cannot open input file

Check that the file name has been correctly entered, that the file exists, and that you have access rights to read it.

Error: Interpretation or data error

Check that the input file is in one of the acceptable formats: PDMS, HPGL or GPGP. If it is, then the file may have been corrupted.

Error: Plot too large for media

Add the ADJUST option to the PLOT command line (see Scaling the Plot to Fit the Paper). The output plot is too large for the actual paper size (if output is to a plotter or printer) or for the defined paper size (if output is to a file).

Error: Unknown device type

Check that the device driver that you have specified matches one of the standard drivers listed in Output Formats That PLOT Can Generate and Running PLOT, or is a valid soft driver name.

Warning: Plot is adjusted to media size

This message confirms that the ADJUST option has automatically rescaled the output plot to suit its destination device or file. No action is needed.
