The MOSEK command line tool Version 7.0 (Revision 141)

14.3. THE STRICT LP FORMAT 295
MSK IPAR READ LP QUOTED NAMES
and
MSK IPAR WRITE LP QUOTED NAMES
allows MOSEK to use quoted names. The first parameter tells MOSEK to remove quotes from quoted
names e.g, "x1", when reading LP formatted files. The second parameter tells MOSEK to put quotes
around any semi-illegal name (names beginning with a number or a period) and fully illegal name
(containing illegal characters). As double quote is a legal character in the LP format, quoting semiillegal
names makes them legal in the pure LP format as long as they are still shorter than 16 characters.
Fully illegal names are still illegal in a pure LP file.
14.3 The strict LP format
The LP format is not a formal standard and different vendors have slightly different interpretations of
the LP format. To make MOSEK’s definition of the LP format more compatible with the definitions
of other vendors, use the parameter setting
MSK IPAR WRITE LP STRICT FORMAT = MSK ON
This setting may lead to truncation of some names and hence to an invalid LP file. The simple solution
to this problem is to use the parameter setting
MSK IPAR WRITE GENERIC NAMES = MSK ON
which will cause all names to be renamed systematically in the output file.
14.4 Formatting of an LP file
A few parameters control the visual formatting of LP files written by MOSEK in order to make it
easier to read the files. These parameters are
MSK IPAR WRITE LP LINE WIDTH
MSK IPAR WRITE LP TERMS PER LINE
The first parameter sets the maximum number of characters on a single line. The default value is 80
corresponding roughly to the width of a standard text document.
The second parameter sets the maximum number of terms per line; a term means a sign, a coefficient,
and a name (for example ”+ 42 elephants”). The default value is 0, meaning that there is no
maximum.
