.IF is a high-level construct, an important element of Macro Assemblers like Masm. You can replace .IF like the following :

include     IFtest.inc

BUFFER_SIZE equ 100

.data

msg1        db 'Please type your name :',13,10,0
msg2        db 'You did not type your name.',0
msg3        db 'Nice to meet you %s',0

.data?

buffer      db BUFFER_SIZE dup(?)

.code

start:

    invoke  crt_printf,ADDR msg1
    invoke  StdIn,ADDR buffer,BUFFER_SIZE

    invoke  StrLen,ADDR buffer
    sub     eax,2   ; remove CR+LF

    .IF eax==0

        invoke  crt_printf,ADDR msg2

    .ELSE

        invoke  crt_printf,ADDR msg3,ADDR buffer

    .ENDIF

    invoke  ExitProcess,0

END start


Converted to :
