Which is why I think that it's better to have them as local functions,
instead of having to introduce a lot of new functions.
Local functions are very pascal-ish. C doesn't have it, which is why they can't
use it.
Let's use the language features to their full extent.
*procedure* SubDomain (*var* x : *array of* Float;
istart : Integer;
ipoints : Integer)
*var*
i : Integer;
*begin*
*for* i := 0 *to* ipoints - 1 *do*
x[istart + i] := 123.456;
*end* /{SubDomain}/;
*procedure* Sub (*var* x : *array of* Float);
/// Variables declared here should have /|*shared*|/ context./
/// This would include the function's parameters then.../
*procedure* SubTask(*var* x : *array of* Float);
*var*
/// Variables declared here have /|*private*|/ context./
iam : Integer;
nt : Integer;
ipoints : Integer;
*parallel*
iam := OMP.Get_Thread_Num; /// OMP library calls./
nt := OMP.Get_Num_Threads;
ipoints := Length (x) *div* nt; /// size of partition/
istart := iam * ipoints; /// starting array index/
*if* iam = Pred (nt) *then*
ipoints := Length (x) - istart; /// last thread may do more/
SubDomain (x, istart, ipoints);
*end*;
*begin*
SubTask(x);
*end* /{Sub}/;
*var*
arr = *array*[0 .. 9999] *of* Float;
*begin* / // Main program/
Sub (arr);
*end*.
