Release Notes
The
following descriptions are cumulative.
Version
4.00c
ELF90 Compiler The
diagnostic for an illegal tab character in a statement field is now
descriptive - previously it was "syntax error". The REPEAT function
is now allowed in an initialization expression.
See Essential LF90
v4.0 Bug Fix Descriptions.
Version 4.00a &
4.00b
Essential Fortran 90 language
subset changes The INTRINSIC statement is allowed. No text
is allowed following the STOP statement. No construct-name can
precede the IF-THEN statement. No construct-name can precede the
SELECT CASE statement. CASE DEFAULT must be the last case if it is
present in a SELECT CASE statement.
ELF90 Compiler The value
of the SIZE argument of the RANDOM_SEED subroutine will now be set to
10, rather than 2. The number of default INTEGERs the processor uses to
hold the seed is 10. We recommend source code similar to the following
to reduce the impact of such changes: PARAMETER ( MAX_SEED_SIZE = 20
) INTEGER SEED( MAX_SEED_SIZE ), SIZE CALL RANDOM_SEED ( SIZE =
SIZE ) CALL RANDOM_SEED ( GET = SEED(1:SIZE) ) CALL RANDOM_SEED ( PUT =
SEED(1:SIZE) )
Running on Windows NT The
new feature of the compiler, linker, and other utilities as native
Windows applications has resolved all known problems with running on
Windows NT.
Filenames containing spaces
Filenames containing a space character must be enclosed in double
quotes as command line arguments to the compiler, linker, etc.
Lahey ED Developer initialization
file The Lahey ED for Windows ini file is now ED4W.ini (the
default name); it was ED4W_ELH.INI previously. When invoking ED4W.EXE,
you do not need to specify an ini file name with the -i switch.
SOLD90 command-line debugger
SOLD90.EXE can only be run on programs linked with the -NWIN option
(note that -WINCONSOLE is the default option).
Essential Lahey Fortran 90 v4.0 Bug Fix Descriptions
The
following descriptions are cumulative.
Fixed in
Version 4.00c
Internal compiler error for statements
with illegal label preceding and ELSE or END IF statement.
Numeric labels are in a random order in
the cross reference (-xref option) listing.
Internal compiler error when WRITE
statement output is ISHFTC with certain constant arguments.
Internal compiler error when argument to
PRESENT function is a function name.
Incorrect diagnostic that derived type is
undefined when the definition succeeds the reference.
Linker error in some cases when path
contains a dot (period) character in the TEMP directory path.
When outputting a value of zero with the
format edit descriptor 'G16.6E2', 6 zeros are printed to the right of
the decimal point; it should be 5 according to the Fortran 90 Standard.
The /EXTRACTALL option of the librarian
(LM) aborts with an invalid record type error.
Incorrect result from MINLOC and MAXLOC
when ARRAY argument contains HUGE values.
REPEAT is not allowed in an initialization
expression.
Incorrect fatal error where ISHFT is used
in an initialization expression.
Incorrect fatal error on initialization
