calling one lisp from within another lisp

Is it possible to call a lisp from within a lisp? if you can could you explain how

Put lisp in () example: (c:practice)

A lisp routine can load another lisp routine and execute functions inside the other routine. The second routine may have to be loaded this way (load"remark.lsp"). I'm not 100% positive on this. Maybe one of our LISP gurus can comment.

yup your right, i found it in the similar threads

may i suggest you also use some thing like this aswell

(if (findfile "Somesortalfile.lsp)
(load (findfile "somesortafile.lsp))
(progn
(alert "\nCan Not find you file, adjust your search paths")
(exit)
)
)

Excuse the format, this thing dosnt tab, when done here

thanks, ill look into that, still learning the error checking stuff
