Perl subroutine returning different values in HPUX
HI ,
I am running a program on hpux in perl.
I am encountering a strange issue where when i print a variable in the sub which is returning it , it prints a different value but when i call it and store value in a variable it gives a different o/p.

the sub is

Code:
sub CheckConfigFilePattern 
{ 
local($FILE) = @_; 
$intLineCount = 1; 
$intSendOpcmon = 0; 
$intCorrectFormat = 0; 

open(CONFFILEHDR, "< $FILE") or die "$!"; 
foreach $strLine (<CONFFILEHDR>) 
{ 
$strLine = trim($strLine); 
if( length($strLine) != 0) 
{ 
print "##############################\n"; 
print "$strLine \n"; 
print "step 0 \n"; 
if( $strLine !~ m/(^#)|(^\s*(\/|\d+)\s+(\/|\d+)\s+(\/|\d+)\s+(\/|\d+)$)/ ) 
{ 
OpcMsg("OS","minor","ConfigFileError","Error in Config File $FILE : Line No. $intLineCount, Text - $strLine","OpC"); 
$intSendOpcmon = 1; 
print "step 1 \n"; 
} 
if ( $strLine =~ m/(^\s*(\/|\d+)\s+(\/|\d+)\s+(\/|\d+)\s+(\/|\d+)$)/ ) 
{ 
$intCorrectFormat = $intCorrectFormat + 1; 
print "step 2 \n"; 
} 
} 
$intLineCount = $intLineCount + 1; 
} 
close CONFFILEHDR; 
if ( $intCorrectFormat != 1 ) 
{ 
OpcMsg("OS","minor","ConfigFileError","Error in Config File $FILE","OpC"); 
$intSendOpcmon = 1; 
print "step 3 \n"; 
} 
print "1st intSendOpcmon: $intSendOpcmon \n"; 

return $intSendOpcmon; 
}

I am printing intSendOpcmon before retruning it inside sub.

Now I am calling it ,

Code:
$intSendOpcmon = CheckConfigFilePattern($CONFFILE); 
if ( $intSendOpcmon = 1) 
{ 
print "2nd intSendOpcmon:$intSendOpcmon \n"; 
exit 0; 
}


But I am getting different values of retruned variable

Code:
#"./cHmem_util.pl" 1 
1st intSendOpcmon: 0 
2nd intSendOpcmon:1

Please check why function is returning different values inside and outside
Code

gappletviewer

GAPPLETVIEWER(1)                                                        GNU                                                       GAPPLETVIEWER(1)

NAME

       gappletviewer - Load and runs an applet

SYNOPSIS

       appletviewer [OPTION]... URL...

       appletviewer [OPTION]... -code CODE

       appletviewer [OPTION]... -plugin INPUT,OUTPUT

DESCRIPTION

       The appletviewer tool loads and runs an applet.

       Use the first form to test applets specified by tag.  The URL should resolve to an HTML document from which the appletviewer will extract
       applet tags.  The APPLET, EMBED and OBJECT tags are supported.  If a given document contains multiple applet tags, all the applets will be
       loaded, with each applet appearing in its own window.  Likewise, when multiple URLs are specified, each applet tag instance is given its
       own window.  If a given document contains no recognized tags the appletviewer does nothing.

               appletviewer http://www.gnu.org/software/classpath/

       Use the second form to test an applet in development.  This form allows applet tag attributes to be supplied on the command line.  Only one
       applet may be specified using the -code option.  The -code option overrides the URL form -- any URLs specified will be ignored.

               appletviewer -code Test.class -param datafile,data.txt

       gcjwebplugin uses the third form to communicate with the appletviewer through named pipes.
