516 True BASIC Language System
Badly formed USING string. (8201)
The format string in your USING$ function or PRINT USING statement is incorrect. Some format item doesn’t follow
True BASIC’s rules. See Chapter 3 and Appendix D for a description of format strings.
Break statement encountered. (10007)
You’ve encountered a BREAK statement in a program-unit in which debugging is active.
Can’t chain from bound program.
You cannot chain from a bound program (one that is directly executable) on some systems.
Can’t continue.
You’ve just given a CONTINUE command, to resume running a suspended program. However, True BASIC cannot continue
the program. There are several possible reasons. You cannot continue a program that you haven’t yet started running,
or one which you’ve just changed. You cannot continue a program which stopped because an error occurred. And
you cannot continue a suspended program after using a DO command. If you are trying to debug a program which stopped
because of an error, try using the BREAK command to insert breakpoints before the erroneous line, and then run the program
again.
Can’t copy region into itself.
The True BASIC editor does not let you copy a region into itself. For instance, you may not make a copy of some subroutine
within that subroutine. If you really want to, you can put a copy of the region somewhere else, and then move this
copy into the original region.
Can’t do graphics on this computer. (-11000)
Your computer cannot draw graphics. Therefore you may not use the SET WINDOW, PLOT, DRAW, BOX, FLOOD,
GET POINT, or GET MOUSE statements.
Can’t edit compiled program.
Your program is compiled, and so cannot be changed. Once you’ve given a COMPILE command, you are only allowed to
RUN, SAVE, or REPLACE the program. If a change needs to be made, call up the uncompiled version and change it.
Can’t ERASE file not opened as OUTIN. (7301)
You may not use the ERASE statement on a file, unless the file has been opened with ACCESS OUTIN. See the OPEN
statement in Chapters 12 and 18 for a description of the OPEN statement and file accesses.
Can’t get STAT info for file in directory. (11270)
The user tried to usea a directory name in the template for Exec_Reader which is not allowed.
Can’t INPUT from INTERNAL file. (7318)
You are trying to use the INPUT statement with an INTERNAL file; use READ instead.
Can’t input from OUTPUT file. (7303)
You may not read input from a file which was opened with ACCESS OUTPUT. If you must read from this file, change
the OPEN statement to use ACCESS OUTIN.
Can’t invert singular matrix. (3009)
You are using the matrix INV function, but the matrix you want to invert is singular. Singular matrices simply have no
inverses.
Can’t open temporary file. (9100)
You are using the file statement ERASE REST. True BASIC requires a temporary file to carry out this instruction, and
had trouble opening one.
Can’t open PRINTER (9101)
You have tried to open the printer but True BASIC has been informed that the attempt has failed, either because the
printer isn’t attached or has not been turned on. (This condition cannot be detected on all machines.)
