Why do I get an error when I try to assign a string value which contains blanks to a TLC variable with the -a option in Real-Time Workshop 5.0 (R13)?

I have a TLC file called test.tlc that looks like:

 %selectfile STDOUT

 MyTestVariable = %<MyTestVariable>

If I execute this tlc file with this command:

tlc -aMyTestVariable="It_works" test.tlc

everything works fine. If I execute the tlc file with this command:

tlc -aMyTestVariable="It does not work" test.tlc

I got the following error message:

 Error: File: execstring Line: 1 Column: 26

 Unterminated string

 Error: File: execstring Line: 1 Column: 29

 syntax error

 Error: Usage: tlc [options] file

 -r <name>specify the record file (.rtw, .mdl, ...) to read

 -v[N]specify the verbose level to be N (1 by default)

 -I<path>specify a search path to look for %include and %generate files

 -m[N|a]specify the maximum number of errors (a is all) default is 5.

 -O<path>specify the path used to create output files

 -d[a|c|n|o|f<filename>]specify debug mode (check assertions, command line debugger,

                        normal, off, or command line debugger batch file name)

 -a<ident>=<expression>assign a variable to a specified value

 -p<number>print a . indicating progress for every <number> lines of TLC code

 -lintperform some simple performance checks and collect some runtime statistics

 -x<number>if <number> = 1 (default) execute all TLC code; if = 0 just parse it

 type "tlc server" for Server Mode usage.

This bug has been fixed for Release 14 (R14). For previous releases, please read below for any possible workarounds:

To assign a string value to a TLC variable, the string inside of the double quotes must be protected by single quotes. For example, the correct format should be:

tlc -aMyTestVariable='"string with spaces"' test.tlc

This will be documented in a future release of the TLC documentation.
