\S1{execute} !execute
\c command
\c command [compare comparevalue | symbol]
This command will execute 'command' using a call to CreateProcess(). Unlike \R{system}{!system}, it does not use the command line processor, so input/output redirection and commands like 'cd', 'dir' and 'type' can not be used. Currently, the only known advantage of \R{execute}{!execute} over \R{system}{!system} is that it does not give trouble when the current working directory is specified using UNC.

This command will execute 'command' using a call to system(). You can store the return value in a define ('symbol') or halt execution if the return value compared (using 'compare') to 'comparevalue' is false. 'compare' can be '<' or '>' or '<>' or '='.
