1. Parameters whose values may be returned by this function include the settings of Mosel as well as those of any loaded module or package. The location of the parameter may be specified by prefixing its name with the name of the module or package defining it ( e.g. mmxprs.XPRS_verbose). The type of the return value corresponds to the type of the parameter.

2. This function can be applied only to control parameters whose value can be accessed.

3. The name argument must be a constant string: a model parameter, variable or string expression cannot be used as a control parameter name.

4. The following control parameters are supported by Mosel:

realfmt	Default C printing format for real numbers (string)
zerotol	zero tolerance in comparisons between reals (real)
ioctrl	the interpreter ignores IO errors (Boolean)
iostatus	status of the last IO operation (integer), which is 0 when the last operation has been executed successfully. This parameter is automatically reset once its value has been read. Not doing so may result in undefined behavior. When ioctrl is active the IO status must be read (and reset) after every IO operation
nbread	number of items recognized by the last read procedure or read in by the last initializations block (integer)
readcnt	generate per label counting when executing `initializations from' blocks (Boolean)
UTC	indicate whether the time functions return time expressed in local (false) or UTC (true) time (Boolean)
autofinal	indicate whether initialisation from blocks are finalizing sets (Boolean)
tmpdir	the Mosel temporary directory (string)
workdir	the current working directory of the model (string)
restrict	active restrictions (integer). See Section mosel command: restricted mode for further details.
modelname	internal unique name of the model being executed.
modelnumber	order number of the model being executed.
recloc	indicate whether automatic recording of source location of constraints definitions is active (Boolean)
localedir	directory where message catalogs are stored (string)
lang	current language (string)
runparams	parameter string used for the current execution (string)
bimprefix	list of bim file prefixes (string)
sharingstatus	sharing status of the model (integer). This parameter is -1 if the model does not share any data; 0 if the model shares data but no submodel is using it; 1 when shared data is in use; 2 if the model is a submodel using shared data (see Section Data sharing between models)

5. Function getparam may also be used to retrieve parser parameters . As opposed to the other parameters whose value is computed at run time, these parameters are evaluated as soon as they are parsed:

parser_line	number of the line being parsed (integer)
parser_file	current source file name (string)
parser_date	current local date (string)
parser_time	current local time (string)
parser_UTCdate	current UTC date (string)
parser_UTCtime	current UTC time (string)
parser_version	Mosel version (string)
model_version	Version of the model as given by the version directive (string)
