System and method for interpreting ASCII code fetched from a code space of a task partition that is part of memory shared by a host processor and a multitask controller (MTC). The MTC includes a scheduler unit, a data flow unit, an executive unit, and a resource manager unit. The shared memory also includes a system partition containing a code space. The fetched code is monitored for adjacent ASCII alphabetic characters and if at least two are found and the fetched code is terminated by an ASCII space character, the code table in the code space of the system partition is scanned to find a command that matches the fetched code. The byte in the table immediately following the matched fetched code and having a bit set indicating that it is interpreted is obtained and written over the ASCII space character in the code space of the task partition.
