Hiya John.
Indices are cool.
How many records we talking about here for the base tables?
More comments below.

[same as first 4]

That should speed things up at a minimum, by a factor of 50 percent.
But - the UPPER(ALLTRIM(___ thing sounds like you got some design changes for acceptable data usage for Accepted/Rejected, right ? why not somewhere give a ONE CHARACTER COLUMN for the ROLLS table that holds A or R [plus what ever else is there] ? Basically - you are doing a string function inside a sql statement, and that eats up processing time, no matter if it has the same index or not.

SO IF YOU HAVE THE ROOM TO ADD ONE MORE COLUMN - do so, and issue three ONE LINE COMMANDS, perhaps prior to your sql select statment ??? [not sure how you want to couple the additional column usage, but this is a one-off, so you can add it in to your design]
select rolls
replace onecolstat with "R" for UPPER(ALLTRIM(cSTATUS))=="REJECTED" and empty(onecolumnStat)

replace onecolstat with "A" for UPPER(ALLTRIM(cSTATUS))=="ACCEPTED" and empty(onecolumnStat)

then going forth ? Take Tore's comment about setting a field value to a variable , for example, ->
lcWorkOrderNo = SALEORDER_ITEMS.cWorkOrderno
SELECT * FROM ROLLS WHERE onecalstat =="R" AND ROLLS.cWorkOrderID == lcWorkOrderNo ORDER BY nRoll INTO CURSOR tmpRejected
