- The internal character are the same as the standard character set.
- Inlength and outlength are equal to 80.
- SYSIN, SYSOUT and SYSERR is connected to standard input,
standard output and standard error.
If they are closed and reopened they are connected to
/dev/tty under UNIX, AIX and MINIX and
sys$input and sys$output under VMS.
- The relative value ranges of real are as double in C and
ranges of integer are as long.
- Conversion from an integer type to a real type are exact except
for implementations where integer have better precision than real
(which is the case for the cray implementation.)
- The effect is not defined if the range of a numeric item in a de-editing
procedure exceeds the value range of the procedure result.
- The exponent from ``putreal'' has 5 characters except
for the cray implementation where it may be 6 characters.
- A text frame has a maximum length of about 64K characters.
- The return values of ``char'' and ``rank'' are as given by the standard
character set.
- The exact definitions of the standard mathematical functions are
system specific.
- The association between a file object and an external file
are standard procedures based on C's FILE.
The object is connected to the external file when open is called.
- Several file objects may represent the same external file,
but the effect is not defined if some of them is opened for writing.
- A minimum of checks are performed at ``locate''.
- The default value to LINES_PER_PAGE is MAXINT.
- The ``basic random drawing'' is implemented as suggested in the standard.
- Two decimals are used for the field for seconds of the function
``datetime''.
- Evaluation of arithmetic expressions are based on C,
but the Simula expression are by default divided up in several expressions,
to guarantee correct evaluation order.
