Sometmes you may find yourself in a situation where you need to assign a value that includes quotes to a string variable, for example when using a command with parameters to be used with LAUNCH EXTERNAL PROCESS. Consider the following command line:

mp3convert.exe -file="test.mp3" -convert_to="Wave" -bits="16" -freq="44100"

The above command uses quotes in its parameters; so in order to assign that to a string variable, special care must be taken for the quotes.

1. The quotes can be escaped with a backslash like this:
   
   

   C_TEXT($myString) $myString:="mp3convert.exe -file=\"test.mp3\" -convert_to=\"Wave\" -bits=\"16\" -freq=\"44100\""

   
   
   
2. The quote can be concatenating in to the string value using the Char command with the character code of the quote:
   
   

   C_TEXT($myString) $myString:="mp3convert.exe -file="+Char(34)+"test.mp3"+Char(34)+" -convert_to="+Char(34)+"Wave"+Char(34)+" -bits="+Char(34)+"16"+Char(34)+" -freq="+Char(34)+"44100"+Char(34)

   
   
   
3. The constant for the double quote can also be used like so:
   
   

   C_TEXT($myString) $myString:="mp3convert.exe -file="+Char(Double quote)+"test.mp3"+Char(Double quote)+" -convert_to="+Char(Double quote)+"Wave"+Char(Double quote)+" -bits="+Char(Double quote)+"16"+Char(Double quote)+" -freq="+Char(Double quote)+"44100"+Char(Double quote)
