## FUNCTIONS ##
|
|
# - functions have their own scopes
|
|
# - they can call other functions
|
|
# - their own vars are private
|
|
# - they can't acces root-scope's vars (except they were made global using `glob`)
|
|
# - args with $-prefix are copied into local scope
|
|
# - args with &-prefix are passed to parent scope
|
|
|
|
# the function scope "myfunction1" starts here
|
|
# argument $1 is readonly; $2 is read/write
|
|
fcn myfunction1 $1 &2
|
|
|
|
# current function scope ends here
|
|
ncf
|
|
|
|
# call a function called "myfunction1"
|
|
# arg $1 = 42; arg $2 = $test (returned to parent scope)
|
