FindIndex question

[Mike Kerner]

i don't know if you dove into the code, but it's too early to think about
unpacking this, so  here's the code:

*## pSearchA is array-valued index for accessing sDataArray*

*## pSearchA[1] = key_1*

*## pSearchA[2] = key_2*

*command* FindIndex pKeyIndexA, pSearchString *--, ...*

*-----*

*local* foundAMatch, theFoundIndex

*local* i

*local* theIndex

*-----*

*repeat* for each key theIndex in sDataArray

*## Developer can pass in multiple search strings to perform an AND search*

*repeat* with i = 1 to the paramCount step 2

*if* sDataArray[theIndex][param(i)] is param(i+1) *then*

*put* true into foundAMatch

*else*

*put* false into foundAMatch

*end* *if*

*## AND search didn't pan out. Move on to next index.*

*if* not foundAMatch *then* *exit* *repeat*

*end* *repeat*

*if* foundAMatch *then*

*put* theIndex into theFoundIndex

*exit* *repeat*

*end* *if*

*end* *repeat*

*return* max(0, theFoundIndex)

*end* FindIndex

On the first day, God created the heavens and the Earth
On the second day, God created the oceans.
On the third day, God put the animals on hold for a few hours,
   and did a little diving.
And God said, "This is good."
