[Simh] Macro-11 Macro library question (RT11 running in SimH PDP11)

[Will Senn]

All,

A couple of questions:

1. Do any of y'all know where there is a working example of an assembly 
language program that includes a user defined macro in a library file?

2. Can you tell me what I'm doing wrong with this simple macro example?

Here's what I tried (that didn't work) after reading the manuals:

edit et2.mac
     .TITLE  ETTYIN
     .MCALL    .TTYOUT,.TIN

START:    MOV    #BUFFER,R1
     CLR    R2
INLOOP:    .TIN    (R1)+
     INC    R2
     CMPB    #12,R0
     BNE    INLOOP
     MOV    #BUFFER,R1
OUTLOOP:.TTYOUT    (R1)+
     DEC    R2
     BEQ    START
     BR    OUTLOOP
BUFFER:    .BLKW    64.
     .END    START

edit tin.mac
.MACRO    TIN    CHAR
     EMT    ^O340
     BCS    .-2.
.IF NB <CHAR>
.IF DIF <CHAR>,R0
     MOVB    R0,CHAR
.ENDC
.ENDC
.ENDM
.END

lib/mac/c tin tin
macro et2/list/cross+tin.mlb/lib
?MACRO-E-Errors detected:  2
DK:ET2,DK:ET2/C=DK:ET2,DK:TIN.SML

The errors are due to the fact that .TIN/TIN (tried it both ways) is not 
found:

       1                        .TITLE  ETTYIN
U     2                        .MCALL    .TTYOUT,.TIN
       3
       4    000000    012701     000036'        START: MOV    #BUFFER,R1
       5    000004    005002                 CLR    R2
OQ    6    000006                INLOOP:    .TIN    (R1)+
       7    000006    005202                 INC    R2
       8    000010    122700     000012             CMPB #12,R0
       9    000014    001374                 BNE    INLOOP
      10    000016    012701     000036'            MOV #BUFFER,R1
      11    000022                OUTLOOP:.TTYOUT    (R1)+
      12    000030    005302                 DEC    R2
      13    000032    001762                 BEQ    START
      14    000034    000772                 BR    OUTLOOP
      15    000036                BUFFER:    .BLKW    64.
      16        000000'                .END    START

However, if I include the macro in the file, edit et1.mac:
     .TITLE  ETTYIN
     .MCALL    .TTYOUT

.MACRO    TIN    CHAR
     EMT    ^O340
     BCS    .-2.
.IF NB <CHAR>
.IF DIF <CHAR>,R0
     MOVB    R0,CHAR
.ENDC
.ENDC
.ENDM

START:    MOV    #BUFFER,R1
     CLR    R2
INLOOP:    TIN    (R1)+
     INC    R2
     CMPB    #12,R0
     BNE    INLOOP
     MOV    #BUFFER,R1
OUTLOOP:.TTYOUT    (R1)+
     DEC    R2
     BEQ    START
     BR    OUTLOOP
BUFFER:    .BLKW    64.
     .END    START

The program compiles/links/and runs fine and whatever strings I enter 
are copied to output as expected. TIN is just the library macro .TTYIN 
copied verbatim. I expect that my macro file is not proper or that it is 
not being found by macro, although it complains if I supply a 
non-existent file.

Insights appreciated.
