The computer will now load "DEPl" into memory in additi on to the program above. After
'"DE Pl .. is loaded, you might fi nd something, in memory, li ke th is:
10 : PRINT .. D EP R EC I AT ION A LLOWANCE'"
20: PRINT .. ENTER YOUR ME TH OD"
30 : INPUT A
10: PRINT '"INTEREST CHARGES"
20: PRINT .. AMOUNT BORROW ED?"
30: INPUT B
( etc)
N otice th ot, unlike the CLOAD command, the ne w progrom did NOT replace the existing one.
Another thing to not ice is that you now have dup li cate line numbers.
At this point you reali ze that the pari of "DEPl" which begins wit h line number 40 is useful IO
the "Depreciation" program you are writing. Simply delete the fi rst three lines of the new
program (starting
wit h 10 : PRINT "INTERE ST CHARGES") and the n ed it the r est of th e new
program to suit your needs. PRESTO, you have saved yourself quite a bit of typing, by using
a common progra.m portion.
Again feel free to experiment. Try merging other program sections.
