** **
** This program is designed to read an input nodelist file and extract **
** selected Networks, Regions and/or Zones. The extracted portions of **
** the nodelist are stored in a file specified on the command line. **
** **
** The format for using this program is as follows: **
** **
** **
** EXTRNETP <srcfile> <destfile> [I] <net1> <net2>...<net20> **
** **
** where <srcfile> is the name of the nodelist file to be read **
** <destfile> is the name of the output file created **
** [I] optionally include all Zone entries **
** <net..> are the numbers of the Net/Region/Zones to be **
** extracted and may include zone specifiers for Nets **
** and Regions (the program is presently set to handle **
** 20 numbers). These numbers may be preceded by a N, **
** R or Z in order to extract the entire Net, Region **
** or Zone. Examples are: 123 N342 n2:201 r17 Z1 **
** **
** **
** The nodelist may be specified with a full drive and path. The **
** destination file must not have a drive or path specified. It will be **
** output to the current directory. **
** **
** The program will display a VERY brief set of instructions if it is **
** called without any arguments or if it encounters an error. The **
** following is a list of the error codes returned by the program: **
** **
** 0 - No errors. Normal termination. **
** 1 - Bad or missing command line argument. **
** 2 - Unable to open the input file. **
** 3 - Unable to open the output file. **
** 4 - Problem writing to output file. **
** 5 - Problem closing input file. **
** 6 - Problem closing output file. **
** 7 - Unable to open configuration file. **
** 8 - Unable to create backup file. **
** **
** When an error is encountered, the program will exit immediately and **
** will attempt to properly close all files. **
** **
