When compiling with optimization level 2, c89 must copy certain files from data sets to HFS files. But c89 could not open the indicated file so it could not copy the corresponding data set to an HFS file.
The error message from the open function is at the end of the c89 message.
In the message text:
string1 is the file name. string2 is the error message.
Try to correct the problem based on the specific error message. If you do not succeed, reenter the c89 command with the -v option and redirect stdout and stderr to a file. Keep this pseudo-JCL and error file and the c89 command specified for problem determination.
Reenter the c89 command. If the problem persists, contact the IBM® service representative responsible for your installation.
