Restore the system defaults for a parameter file from S-Lang.
punlearn( paramfilespec )
This function is essentially the same as the command-line
version (see "ahelp tools punlearn"). To use it
the paramio module must have been loaded.
The input value can be one of:
-
a string containing a single name
-
a string containing multiple names, each separated by
a space or a comma
-
an array of strings, each string being the name of a single parameter file
Note that punlearn() does not accept a Param_File_Type variable -
i.e. the output of paramopen().
As with all the paramio routines, the PF_Errno variable
is set to 0 on success, or on error it is set to
one of the error codes listed in the paramio documentation.
chips> require("paramio")
chips> punlearn("dmextract")
chips> punlearn("dmextract dmlist")
chips> punlearn("dmextract dmlist, dmcopy")
chips> punlearn(["dmextract","dmlist","dmcopy"])
This example shows the different ways that
punlearn() can be used.
