System Messages
The FORTRAN run-time library displays the messages in this and the following
subsections if an error occurs while executing a statement or intrinsic routine. The error
might be detected by the operating system, by routines in the FORTRAN run-time
environment, or by routines in common run-time environment.
System Messages With ENV OLD
If your program specifies ENV OLD and an error occurs while running your program,
the FORTRAN run-time library writes a message to your log file according to the format
described earlier in this section. However, the message specifies only the file system
error number that occurred—there is no message text.
System errors can occur in programs that specify ENV OLD on the following
statements and utility routines:
BACKSPACE FORTRANSPOOLSTART POSITION
CHECKPOINT INQUIRE REWIND
CLOSE OPEN STARTBACKUP
ENDFILE
System Messages With ENV COMMON
If your program specifies ENV COMMON and an error occurs while running your
program, the FORTRAN run-time library writes a message to the standard log file
according to the format described earlier in this section. The following subsections
show the text of the messages that FORTRAN writes.
