Can't modify single ref constructor in scalar assignment

Can't modify single ref constructor in scalar assignment

Can't modify single ref constructor in scalar assignment

(OP)
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

RE: Can't modify single ref constructor in scalar assignment

"\$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:
my $tmp = "data"
$data_dir = \$tmp;

then to print out what $data_dir refers to:
print $$data_dir;

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.
