Limit to variables passed to a function

When there's a limit for the length of a line then this may be the limit. Other than that I am not aware of any limit, although it wouldn't be surprising if there's some kind of max, within the range of reason.

you may try this:

wr=writefile("test.bb")

l$="dummy=test("

ma=10000 ;test 10 thousand arguments...
for i=0 to ma
 l$=l$+rand(10)+","
next
l$=l$+rand(10)+")"

writeline wr,l$
writeline wr,"waitkey()"
writeline wr,"end"

l$=" function test("
for i=0 to ma
 l$=l$+"x"+i+","
next
l$=l$+"x"+(ma+1)+")"

writeline wr,l$
writeline wr,"End Function"

closefile wr
