This sounds best handled as an initial -generate-
followed by a series of -replace ... if ...-.
That is not to rule out the usefulness of -assert-.
Be aware also of -max()- and -cond()-. In the latter
case there is a leisurely tutorial:
SJ-5-3 pr0016 . . Depending on conditions: a tutorial on the cond() function
