If your version of the QUEST software does not operate perfectly you should read this appendix.

Suggestions are provided which should solve most of the problems you might encounter.

Problem 1 I don't get pictures or menus, just streams of strange characters, eg.

	<SCREEN>	G7hf @

Solution 1a Your terminal may not be in Tektronix mode. Find out how to use the "setup" procedure on your terminal or emulator, and ensure that you have entered Tektronix mode before running the software.

Please inform the CCDC of the terminal or emulator you are using - if there is sufficient demand then there could be an EMULATOR command for your terminal in the next QUEST software release.

Solution 1b This is much rarer than 1a.

If your computer is a non-ASCII and non-EBCDIC machine then it is possible that the subroutine GL002 is incorrect. You should consult the installation notes or ask the person who installed the software to do so, and run the TESTCARD using TERM TEST.

Problem 2 With an emulator, when I use the cursor to select a point on the screen, QUEST does not seem to recognise this.

Solution 2 On 4010/4014 and 4100 Series Tektronix terminals QUEST expects a space and <carriage return><line feed> to be used to terminate the GIN (graphic input) report. This is the standard Tek terminator.

If someone has changed this setting on your emulator you may have to find out how to change it back again. Consult your local expert.

On 4200 Series terminals the EOL string is set to `.<carriage return>' by the software, using the standard Tektronix escape sequence. You may have to do this manually using your emulator, if it does not recognise the Tektronix sequence. Again, consult an expert - the ASCII characters you require are 46 and 13 respectively.

Problem 3 I have initiated QUEST but have not yet started up the graphics. When I type "HELP" I get no response, but a dagger prompt ">" is displayed.

Also when I initiate the graphics and use the option "TYPE" I get no response and, if I make a mistake, the program does not allow me to "try again".

Solution 3 Quest has not been able to determine that the software is running interactively - see the Installation notes for the Machine-Independent Package.

Before doing anything else, you should type "INTER" (meaning INTERACTIVE). Then HELP, TYPE and also INFO should function correctly.

Problem 4 On a VAX, I type QUEST to run the program and I get the following message:

	<SCREEN>	%DCL-W-IVVERB, unrecognised command verb - check validity and spelling

Solution 4 You have not typed CSD.

See Appendix 12 - Notes for VAX Users.

Problem 5 On a VAX, the terminal screen does not seem to be cleared correctly with the result that the the diagrams for `hits' are superimposed on top of each other.

Solution 5 For the TEK instruction "PAGE" to be interpreted your VAX must know the kind of terminal (device type) you are using.

Either issue the command

	<PROMPT>	$ SET TERMINAL/DEVICE= [appropriate device type]

Problem 6 On a Silicon Graphics or SUN workstation, I type quest to run the program and I get the following message:

	<SCREEN>	quest: Command not found.

Solution 5 You have not issued the source command, to set up the alias and environment variables required to run QUEST. See Appendix 13 - Notes for Silicon Graphics and Sun users.
