getparam

Purpose
Get the current value of a control parameter.
Synopsis
function getparam(name:string):integer|string|real|boolean
Argument
name 
Name of the control parameter whose value is to be returned (case insensitive).
Return value
Current setting of the control parameter.
Example
Setting and retrieving values of control parameters 
r:=0.123456789
setparam("realfmt", "%.5f")
writeln("r=", r)              ! Output: r=0.12346
writeln("Model ", getparam("modelname"), " version:", getparam("model_version"))
Further information
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 (see detailed documentation in Chapter Control parameters):

autofinal whether initialisation from blocks are finalizing sets
bimprefix list of bim file prefixes
ioctrl whether the interpreter ignores I/O errors
iostatus status of the last I/O operation
lang current language
localedir directory where message catalogs are stored
mathctrl whether the interpreter ignores maths errors
modelname internal unique name of the model being executed
modelnumber order number of the model being executed
nbread number of items recognized by the last read or 'initializations from'
readcnt generate per label counting when executing `initializations from' blocks
realfmt default C printing format for real numbers
restrict active restrictions
recloc activate automatic recording of source location of constraint definitions
runparams parameter string used for the current execution
sharingstatus sharing status of the model
tmpdir the Mosel temporary directory
txtztol zero tolerance for converting real values to their textual representation
utc whether the time functions return time expressed in local or UTC time
workdir the current working directory of the model
zerotol zero tolerance in comparisons between reals


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:

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