H.3 Passing Clusters to Routines |
Below in the editor is an example of a routine that calculates tax. We will pass into the routine a cluster that contains the amount and the tax rate. The routine will return the tax due.
A routine having a cluster passed to it has full access to the cluster for both reading and writing. This includes being able to add new rows to the cluster, performing collect/end collect operations, etc.
Simplified Cluster Parameters
Just like simple parameters, cluster parameters can also be simplified if the root cluster contains data. In this example, the root cluster is called taxes and is both a parameter name and a cluster name.
cluster taxes: name$, profit, tax_rate
taxes->name$ = 'Sally Sue'
taxes->profit = 1234
taxes->tax_rate = 6.5/100
calculate_tax_due with taxes, returning due
print 'Tax due:'; due; 'for '; taxes->name$
private routine calculate_tax_due with taxes, returning due
due = taxes->profit * taxes->tax_rate
end routine
