Remarks:

IG_ISIS_env_get reads the value of an entry in the ISIS scanning configuration file SETSCAN.INI.

Use IG_ISIS_env_get to read from the scanning configuration file. If you are creating your own scanner selection dialog, you should read from and write to the same sections and entries used by the standard scanner selection dialog in order to ensure compatibility with other ISIS applications. For keeping track of non-scanning related parameters or those scanning parameters that are specific to your application, you should use your own custom INI file.
