A.

Gopen (filename1.dat, f1-handle)

Gunzip (filename2.gz, f2-handle)

Compare (f1-handle,f2-handle,2,3)

Save (f1-handle, filename-compare.gz)

B.

C.

Gunzip (filename1.gz, f1-handle)

Gunzip (filename2.gz, f2-handle)

Join (f1-handle,f2-handle,1,2,True)

Save (f1-handle,filename-join.dat)

Explanation / Answer

in (A)
Gopen (filename1.dat, f1-handle)

Gunzip (filename2.gz, f2-handle)

Compare (f1-handle,f2-handle,2,3)

Save (f1-handle, filename-compare.gz)

there is error at line 4 in the command Save (f1-handle, filename-compare.gz)

since save is used to save the files in umcompressed format so the command should be Save (f1-handle, filename-compare.dat)

in  (B).

Gunzip (filename.dat,fn-handle)

Find (fn-handle,1,”Searchers”)

Save (fn-handle, filename-searchers.dat)

there is error in line command Gunzip (filename.dat,fn-handle)

since Gunzip is used to create a normal file from the compressed file

so the correct command should be Gunzip (filename.zip,fn-handle)

C.

Gunzip (filename1.gz, f1-handle)

Gunzip (filename2.gz, f2-handle)

Join (f1-handle,f2-handle,1,2,True)

Save (f1-handle,filename-join.dat)

there is error in command Join (f1-handle,f2-handle,1,2,True)

since true should in double quotes do , the correct command is Join (f1-handle,f2-handle,1,2,"True")
