about assembler language How do I output a space between val

about assembler language, How do I output a space between values? Is there any command like\'call ...\' to do that? Because i don\'t want to change the eax value to interrupt the compute process. Thanks

Solution

in the .data portion and use it to print a space. It should work.

SPACE MACRO
   MOV DL, \' \'
   MOV AH, 02H
   INT 21H
ENDM

add this macro to your program and just use the word SPACE to invoke it.
