?!? – SIZE sets the number of data registers. If the highest register number used by your program is 25 then you need to set SIZE 026 (or more). But unless you run the program and R25 is actually accessed you can set any SIZE you want, even SIZE 000. It doesn't matter whether you enter the program by hand or you read a card, use the barcode reader or a tape drive.

But this SIZE 026 setting can be related to something completely different: if you read a card with a HP67 program (!) this program may require SIZE 026 because the HP67 has 26 data registers. The last one, register I, is number 25 which leads to SIZE 026. But this does not have anything to do with a general requirement of SIZE 026 if a program card is read.

However, a > 800 step program does not sound like a HP67 program. Does the documentation of your program actually say that SIZE 026 is required? What is the highest register number that is used?
