Code:

MVC STR1,STR2

DS  STR1  CL10
..
..
DS  STR2  CL4
DS  STR3  CL8
..


Suppose Str1 = '0123456789', Str2 = 'abcd', Str3 = 'efghijkl'. After the move, Str1 = 'abcdefghij'. How can I make Str1 = 'abcd______' (str2 padded with 6 blanks)?

fill STR1 with blanks before the move
Code:

 MVI STR1,C' '
 MVC STR1+1(L'STR1-1),STR1

(That syntax may be off, but that is the idea... I haven't done much assembler lately)

... and then MVC STR1(4),STR2

In other words, you need to specify the length if it's not 10.

By the way, you've got DS and STR1, STR2, STR3 the wrong way round.
