I have some unrolled loops that look a bit like this, with the loop body in a macro 'TDMR1COL'.

Code:

move.l      .td_mr1_jt(pc,d5.w),a5
jmp         (a5)

.td_mr1_jt:
dc.l        .td_mr1_1
dc.l        .td_mr1_2
dc.l        .td_mr1_3
dc.l        .td_mr1_4
dc.l        .td_mr1_5
dc.l        .td_mr1_6
dc.l        .td_mr1_7
dc.l        .td_mr1_8

TDMR1COL:    MACRO
.td_mr1_\1: ...
ENDM

TDMR1COL    8
TDMR1COL    7
TDMR1COL    6
TDMR1COL    5
TDMR1COL    4
TDMR1COL    3
TDMR1COL    2
 TDMR1COL    1

Is there a way to set up something like this with a REPT (or two) in vasm? I can't see a way to construct the .td_mr1_X labels automatically by including a symbol generated from the repeat count in a label name, either a REPTN or a SET-value.
