General errors

These errors may occur either during compilation or when running a model.

E-1   Internal error in `location' (errortype)

An unrecoverable error has been detected, Mosel exits. Please contact Xpress Support.

E-2   General error in `location' (errortype)

An internal error has been detected but Mosel can recover. Please contact Xpress Support.

E-4   Not enough memory

Your system has not enough memory available to compile or execute a Mosel model.

E-21   I cannot open file `file' for writing (driver_error)

Likely causes are an incorrect access path or write-protected files.

E-22   I cannot open file `file' for reading (driver_error)

Likely causes are an incorrect access path or filename or not read-enabled files.

E-23   Error when writing to the file `file' (driver_error)

The file could be opened for writing but an error occurred during writing (e.g. disk full).

E-24   Error when reading from the file `file' (driver_error)

The file could be opened for reading but an error occurred while reading it.

E-25   Unfinished string

A string is not terminated, or different types of quotes are used to indicate start and end of a string.

Example:

 writeln("mytext)

E-26   Identifier expected

May occur when reading data files: a label is missing or a numerical value has been found where a string is expected.

Example:

 declarations
  D: range
 end-declarations

 initializations from "test.dat"
  D
 end-initializations

Contents of test.dat:

 [1 2 3]

The label D: is missing.

E-27   Number expected

May occur when reading data files: another data type has been found where a numerical value is expected.

Example:

 declarations
  C: set of real
 end-declarations

 initializations from "test.dat"
  C
 end-initializations

Contents of test.dat:

 C: [1 2 c]

c is not a number.

E-28   Digit expected for constant exponent

May occur when using scientific notation for real values.

Example:

b:= 2E -10

E must be immediately followed by a signed integer ( i.e. no spaces).

E-29   Wrong file descriptor number for selection (num)

fselect is used with an incorrect parameter value.

E-34   I cannot find IO driver `driver'

The system cannot locate the IO driver driver for opening a file. This may happen if the driver is provided by a module not already loaded in memory. To avoid this problem the module name should be given with the driver name. For instance use "mmodbc.odbc" instead of "odbc" alone.

E-35   Error when closing file `file' (driver_error)

An error occurred while closing a file. Typically the last write operation for clearing buffers failed.

E-36   Read error (file)

I/O error during file reading.

E-37   Invalid character

Invalid character sequence found while reading a text file, non-conforming to the current encoding. Possibly an incorrect encoding (Mosel default is UTF-8) has been specified for accessing this file.

E-38   Unknown compiler flag(s) `flag' ignored

Some of the flag(s) used with compile have not been recognized, please refer to the list documented for compile.

E-39   Unknown BIM reader flag(s) `flag' ignored

Some of the flag(s) used with load have not been recognized, please refer to the list documented for load.

E-40   Unsupported encoding `encoding' (ignored)

The encoding name specified after the marker !@encoding is unknown.
