Nested FORs are not allowed (E62) You attempted to execute a standard FOR within another standard FOR. Suggested actions: • Replace the outermost FOR with a multi-line FOR. You could also try to replace it with a loop. No help available (E64) MacDOS did not have a help entry for what you required. Suggested actions: • Type "HELP ?" to obtain the list of the help entries available. • When asking for help about a MacDOS filter, check that the name is correct. No such volume (E50) MacDOS did not find the volume that you specified in one of your commands. Perhaps you trashed a volume but thought that you were only ejecting it. Suggested actions: • Check whether you should re-mount a volume which was erroneously dismounted. Not a directory (E11) MacDOS found a file when it expected to find a folder. You must have passed to a command a filename instead of the name of a folder. For example, you might have attempted to delete a file with RMDIR, to copy it with XCOPY, or to rename it with RENDIR. Suggested actions: • Check the on-line help for the command which failed. You can delete a file with DEL, copy it with COPY, and rename it with RENAME. Not a file of type 'TEXT' (E40) MacDOS found a non-text file when it expected to find a text file. You probably passed the name of a data or application file to commands like TYPE or MORE. Suggested actions: • If you want to display the content of a binary file, use the command TYPE with the switch /H or /R. Not a licence number (E68) MacDOS expected to be given a licence number but received a string which did not have the correct format. MacDOS then runs in demonstration mode. This error message has become obsolete with MacDOS 2.0. Therefore, it should have not happened. Suggested actions: • Remove the old versions of MacDOS from your system, so that you always execute the latest version. Not enough memory (E69) Your Macintosh does not have enough memory to support a MacDOS memory partition. Suggested actions: • Click once on the icon of MacDOS and type cmd-I to obtain the Info-box of MacDOS. This will tell you how much memory is necessary to run MacDOS. • If you are running system 6 without multifinder, the only solution is to add more memory to your Mac. • Quit one or more applications running under multifinder or system 7, so that enough memory becomes available. As the Mac OS does not rearrange memory partitions, you should first quit the application that you launched last and then progressively quit older applications. Not enough space in the heap (E16) MacDOS could not allocate dynamic memory to store temporary data. Commands which need more memory than others are COPY, DIR, and FOR. MacDOS also uses dynamic memory to execute batch programs and store global variables. Suggested actions: • When copying wildcarded files with COPY, try to break down the copying into two or more separate commands (eg. A* could be split into A*1* and A*2*). This will reduce the number of filenames temporarily stored during the copy. • If you were CALLing batch programs from within other batch programs, try to reduce the 'depth' of the calls. This will reduce the number of batch files simultaneously open and for which MacDOS needs to keep data in memory. • If you were executing a FOR, try to tighten up the wildcarding or to break it into more than one loop. This will reduce the number of filenames temporarily stored in each loop. • It might be useful to get rid of global variables which have been left behind by previous batch programs. • Increase the size of the MacDOS partition by changing the Preferred and/or Minimum Size shown in the Finder Info-box. Path with two consecutive backslashes (E21) Suggested actions: • Check the path. Port does not exist at destination (E84, destPortErr) During execution of a command containing pipes, either MacDOS or one of the filters did not succed in sending a message to a filter. Suggested actions: • While developing a filter, you have probably failed to initialise the pipes. Please refer to Appendix B for help. PPC Port already open. Restart the Mac if you need piping. (E95, portNameExistsErr) During execution of a command containing pipes, one of the filters did not succeed in opening its PPC port. Suggested actions: • If you were developing a filter, you have probably exited the application without going through the appropriate procedure declared in pipe.h. Please refer to Appendix B for help. Unless you want to change the name of your filter, you will have to restart the Mac. Remote process does not respond (E97, pipeTimeoutE) During execution of a command containing pipes, MacDOS timed out while waiting for a message from a filter. Also refer to Appendix B. Suggested actions: • Perhaps one of the filters is taking longer than expected to process and forward a message. Increase the timeout in seconds by setting the global variable TIMEOUT. • If you are developing a filter, perhaps you have erroneously dropped a message. Remember that you have to forward to the outgoing pipe a message for each message that you receive from the incoming pipe. • If you are debugging a filter, perhaps you have prevented it from replying by setting a breakpoint. Increase the timeout by setting the global variable TIMEOUT to a high number of seconds. Requested variable has not been defined (E63) MacDOS could not find the global variable you used in a command. Suggested actions: • Type SET without parameters to see the list of the global variables currently defined. • Perhaps you forgot to set the variable before executing the command or mistyped its name in the command. • Remember that user-defined global variables are totally removed from the system if you set them to nothing (eg. SET VNAME= with no value after the equal sign). Response addressed to a filter (E94, pipeFilterRespErr) During execution of a command containing pipes, one of the filters received a response message with its address as destination. Suggested actions: • You have probably caused the problem by incorrectly updating pipe.c or pipe.h. You should not modify those files. Please refer to Appendix B for help. Session was closed (E86, sessClosedErr) During execution of a command containing pipes, either MacDOS or one of the filters did not succeed in sending a message to a filter. Suggested actions: • The destination filter probably failed and exited without reporting an error back to MacDOS. Please refer to Appendix B for help. Sorry, the operation you have requested needs System 7.0 or greater (E82) You attempted to use MEM, RESTART, or SHUTDOWN under System 6. Suggested actions: • What about upgrading to System 7 ? Source and destination must be different (E71) You attempted to XCOPY a folder onto itself. Suggested actions: • Check where you are. MacDOS assumes the current folder as default if you do not specify a path. You might have also swapped source and destination (the format is "XCOPY from to", not "XCOPY to from"). Standard FOR cannot execute an IF command (E78) You attempted to execute an IF command after the DO keyword of a single-line FOR. Suggested actions: • Replace in your batch program the standard FOR with a multi-line FOR as follows: for %var in (theSet) do if ...%var... becomes: for %var in (theSet) do begin if ...%var%... next var set var= • If you were executing the FOR interactively, replace it with a short batch program String search failed (E72) MacDOS did not find the requested substring in a string variable. Suggested actions: • Check the variable name and the delimiter. • If the error was reported when executing SSTR and you are convinced that it should have succeeded, type SET without parameters to obtain a list of all the variables and their values. • If the error was reported when executing DECR, check that you typed the BY-string in the correct upper and lower cases. Syntax: double input redirection (E7) You can only redirect the input once. Remember that a command which follows a pipe has its input redirected. An explicit input redirection would cause this error message to be issued. Suggested actions: • Recall the command with up-arrow and delete one of the redirections. Syntax: double output redirection (E8) You can only redirect the output once. Remember that a command which precedes a pipe has its output redirected. An explicit output redirection would cause this error message to be issued. Suggested actions: • Recall the command with up-arrow and delete one of the redirections. Syntax: invalid arguments (E13) Not enough or too many parameters and switches for the command you executed. Also, you might have passed the wrong type of parameters (eg. a non-numeric fileID to READ). Suggested actions: • Check with the on-line help what combinations of parameters and switches are legal. Syntax: invalid format (E12) You typed a badly formatted command. Suggested actions: • Check that your command did not start with a redirection. • Check that each redirection token (ie. '<', '>', '>>', and '|') is immediately followed by the appropriate string. The character requested for quoting is not free (E81) You attempted to set the global variable QUOTE to a reserved character. Reserved characters are: all non printing characters, the space character, the exclamation mark ('!'), the slash ('/'), and the three characters used for redirection and piping ('<', '>', and '|'). The file is not executable (E22) MacDOS can launch applications and AppleScripts or execute text files as batch programs. You directed MacDOS to execute a file which was of the wrong type. Suggested actions: • Use the command DIR to list the content of the folder which should contain the executable file; then check the filename. • If the executable file was supposed to be in a folder identified through the system variable PATH, use the command ECHO %PATH% to display the current path and check that the folder is correctly specified. • If you wanted to execute a batch program named "whatever.BAT" and only typed after the prompt 'whatever', check that there is no file named 'whatever' in the same folder. If that is the case, you must type the full name of the batch file (ie. "whatever.BAT") in order to execute it. The pasting of newline characters into the command string is not allowed (E39) MacDOS does not allow you to paste into the command line more than one line of text. In some cases, you can also get this error message if you hit the return key after MacDOS has displayed a warning. The path contains too many characters (E83) While executing MEM, MacDOS found that the path of one of the application files was too long to be displayed. The startup volume cannot be unmounted (E61) You attempted to unmount with the command EJECT the volume which contains the running OS. Suggested actions: • Use the command EJECT/E to put the startup disk off line without unmounting it. This Mac does not support PPC (E98, pipeNoPPCErr) Your Mac does not support the Process to Process Communication toolbox (PPC). Therefore, you cannot use pipes in your commands except to drive MORE. Too many characters in command line (E37) MacDOS counted more than 199 characters in a line of commands. Suggested actions: • Try to break the line into two separate commands: • If the line contains the command MORE, use an intermediate file and separate output and input redirection instead of a pipe. • If you have a long list of files to copy, split the list of filenames. • If the length is due to a couple of long paths, use CHDIR to move to an intermediate folder where the total length of the paths become shorter (note that a "directory-up" in a path only requires two dots, while a "directory-down" requires the full name of the folder). Too many labels (E45) MacDOS found more than 64 labels in a single batch file. MacDOS automatically creates a label for each FOR- NEXT pair. Therefore, when counting the labels in a batch file you should also count the multi-line FORs. Suggested actions: • Remove from the batch program all the labels which are not used. • Do not use a multi-line FOR when a standard single- line FOR can do. • Break the batch file into two separate files by writing the name of the second file as last command of the first one. Pay attention not to split FOR- NEXT pairs and keep all labels together with the corresponding GOTOs. • Extract parts of the batch file which are self- contained and form other batch files which can be CALLed by the main program. Too many levels of batch CALLs (E30) The number of CALL levels cannot exceed 16. Suggested actions: • Check whether you can merge a called batch file into the calling one. • If a CALL is the last command in a batch file, just replace it with the called filename. Too many sorting requests (E29) The number of sort options in a DIR command cannot exceed 16. Suggested actions: • You must have duplicated options, because the total number of options supported is less than 16. MacDOS executes the options in the order in which they are given, from left to right. Therefore, only the rightmost option of each type performs useful work. Get rid of the others. • If the rightmost sorting option is a sorting by name, you can remove all the preceding options. They are totally irrelevant, because filenames are unique and a sorting by name certainly overrides all previous sorts. Unexpected data message from a filter (E99, pipeSurpriseDataE) While performing a command containing pipes, MacDOS received a data message from a filter before it could complete the configuration of the filter chain. Suggested actions: • You have probably caused the problem by incorrectly updating pipe.c or pipe.h. You should not modify those files. Please refer to Appendix B for help. Unknown pipe command (E89, pipeUnknownMessErr) During execution of a command containing pipes, either MacDOS or one of the filters received a message of an unknown type. Suggested actions: • You have probably used the wrong command code while modifying pipe.c or pipe.h. You should not modify those files. Please refer to Appendix B for help. User Cancelled (E36) You aborted a piped command with a cntl-C or cmd- Period. Variables used in iterations must be unique (E66) MacDOS found in the same batch program two REPEAT commands referring to the same label. Suggested actions: • Replace the REPEATs with GOTOs. Volume literal ID not assigned (E60) MacDOS did not find a literal volume ID in its list of definitions. Suggested actions: • Type SUBSTVOL without parameters to have a list of all literal IDs which have been assigned. • Change the command to use the correct ID or use SUBSTVOL to assign the missing ID to the appropriate volume. Volume offline (E4) MacDOS could not complete an operation because the volume specified in your command was off-line. You probably have typed cmd-dot when the Mac OS asked you to insert a particular floppy. Suggested actions: • Insert the requested cartridge to mount the volume or use another volume. Wrong destination in pipe message (E87, pipeAnotherDestE) While performing a command containing pipes, MacDOS received from a filter a message not directed to MacDOS. Suggested actions: • While developing a filter, you must have send a message to a filter ID which does not exist. Please refer to Appendix B for help. Wrong volume specification (E19) MacDOS detected an invalid volume ID. Valid volumes IDs are numbers between 1 and 31 and single letters between A and Z (case insensitive). Suggested actions: • Replace the volume ID in your command with a valid ID. (Data message correctly received) (E91, pipeReturnE) (Do not report this) (E42, pipeDoNotReportE) (file not found) (E35) (PPC Operation not completed) (E88) (wrong file creator) (E54) (wrong file type) (E55) These error messages refer to error codes which are used by MacDOS internally. Therefore, you should never see them. Suggested actions: • Please report this occurrence to Rainbow Hill. Try to provide as much information as possible about the circumstances.
