Can't modify single ref constructor in scalar assignment

calabama · Feb 21, 2001

Does anyone know where I could locate ActivePerl Diagnostic and ErrorMessage documentation.

I'd like to locate a means to a solution for this error.

I have only found one(1) reasonable thread related to this topic:

http://mailarchive.activestate.com/mail/msg/perl5-porters:468392

when searching the internet for this error:
Can't modify single ref constructor in scalar assignment at
C:\WINDOWS\TEMP\DzTemp.pl line 5, near ""data";"

resulting from the folowing line of perl code:
\$data_dir = "data"; # data directory like "data"

Any line of code which includes an escape character before a $variableresults in the same error followed with:
Execution of C:\WINDOWS\TEMP\DzTemp.pl aborted due to compilation errors

I am Using:

ActivePerl /Build 623
DZSOFT Editor 4.0
Windows 98

"\$data_dir" is the address of "$data_dir", i.e.
"SCALAR(0xf00a89fc)" , and it doesn't take well to being told to reassign itself to "data". if you want $data_dir to be a reference to a string, try:[tt]
my $tmp = "data"
$data_dir = \$tmp;[/tt]
then to print out what $data_dir refers to:[tt]
print $$data_dir;[/tt]
however, scalar references aren't really needed in perl, as a reference itself is stored as a scalar, so you might as well just have the value there and skip the extra step. "If you think you're too small to make a difference, try spending a night in a closed tent with a mosquito."
