http://www.cadfamily.com/downinfo/300868.htmlQuoting your string-variablesWithin the perl scripts, it is required to use vertical quoted strings ('
' or"" ) wherever the chosen value happens to be a perl command, otherwise yourscript will not run correctly.
Within the perl scripts, it is highly recommended that youquote all strings to reduce the possibility of generating errors. In perl, single quotes (' ') represent text as is, with no variable substitution. Double quotes ( "") perform variable substitution. For example, "$myVar" will be substituted by its value if itis in double quotes, while '$myVar' will just be equal to $myVar if it is in single quotes.
