When compiling with optimization level 2, c89 must copy certain files from data sets to HFS files. But it could not write to the indicated HFS file, which is an output of the c89 command, so c89 could not copy that file from a data set.
The error message from the write function is at the end of the c89 message.
In the message text:
string1 is the data set name. string2 is the file name. string3 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.
