subroutine loc.by.fld (dyn.array, siz, start.field, val, expr, ret.field)
* Searches through dynamic array dyn.array, of size siz, starting
* at field start.field,
* and returns the ret.field which is the field whose value val
* is equal to expr.
* Starts search at field specified
* Returns 0 if not found.
* This is like an execution of select, find me the field whose third value
* is this expression.
* Weakness - doesn't handle subvalues.
start.from = if start.field <= 1 then 1 else start.field
ret.field = 0
* print @(0,22):@(-3):@SYS.BELL:"LOC.BY.FLD called."
for i = start.field to siz
while ret.field = 0 ; * For efficiency - return first hit
if dyn.array<i,val> = expr
then
ret.field = i
end
