sometimes reading the manuals can yield the strangest things. looking for something entirely different, the function EXCL:LOAD-COMPILED came up, and it looked kind of strange, so in case those who have complained vociferously about the lack of COMPILE-FILE in the Windows demo version of Allegro CL, the Lite edition, would be pacified by the existence of this function, here's the documentation:
Compiles and loads the file specified by the filename argument but does not write a fasl file. This function is intended for use with certain trial versions of Allegro CL in which COMPILE-FILE (and friends) are disabled. This function takes a filename and any number of keys that are appropriate for COMPILE-FILE. Users who have access to COMPILE-FILE need not use this function.
