System Error Message Format
p-addr
is the program location, in octal, where the error was detected, as shown by the
instruction address in the P-register.
space
is the two-letter code space identifier as follows:
UC User code SC System code
UL User library SL System library
segment
is the segment number, in octal, within space.
uuu
is the number of the unit specified in the READ or WRITE statement. Unit number
000 indicates an error on $RECEIVE; an all blank unit number refers to an internal
file.
errno
is a 5-digit number that identifies the I/O error.
Errors 00001 through 00255 are file-system error numbers. For more information about
file system error numbers, see the Guardian Procedure Errors and Messages Manual .
You can get a brief description of file system errors by entering the following TACL
command:
ERROR error-number
Errors 00256 through 00274 are unique to the formatter. See Formatter Run-Time
Messages on page G-8.
System Error Message Format
The FORTRAN run-time-library writes an error message to the log file in the following
format if either the run-time library or the Guardian file system detects an error while
executing an I/O statement, other than a READ or WRITE statement, or START
BACKUP or CHECKPOINT statement:
operation ERROR @ space. seg p-addr IN process-id
UNIT uuu, ERROR errno
