MyExecutable.cgi 
How can I imitate this behavior in a bash script?

I tried invoking them as two separate system commands by using backquotes `, but the second command will not remember the previous one

Code:
export QUERY_STRING="workdir=/u/here/there/&nb1=5&nb2=1000"
MyExecutable.cgi

Also, what if the value of nb1 is in fact a $variable and not 5, would that cause problems?

It shouldn't, though it could depend on the contents of the variable.

NAME
cgi_init - Initialize ClearSilver CGI environment SYNOPSIS
#include <cgi/cgi.h> NEOERR *cgi_init (CGI **cgi, HDF *hdf); ARGUMENTS
cgi - a pointer to a CGI pointer hdf_file - the path to an HDF data set file that will also be loaded into the dataset. This will likely have to a be a full path, as the HDF search paths are not yet set up. Certain things, like DESCRIPTION
cgi_init initializes the ClearSilver CGI environment, including creating the HDF data set. It will then import the standard CGI environ- ment variables into that dataset, will parse the QUERY_STRING into the data set, and parse the HTTP_COOKIE into the data set. Note that if the var xdisplay is in the form data, cgi_init will attempt to validate the value and launch the configured debugger on the CGI program. These variables have to be specified in the hdf_file pointed to by hdf_file. The default settings do not allow debugger launching for security reasons. RETURN VALUE
cgi - an allocated CGI struct, including SEE ALSO
