| 18 | ! one with this base, since PHASE a. assumed to be FIXED),
|
|---|
| 19 | ! after this, for atoms branching from this base:
|
|---|
| 20 | ! for a b.angle & b.length with common primary moving
|
|---|
| 21 | ! atom=branch atom - b.angle comes 1st
|
|---|
| 22 | !
|
|---|
| 23 | ! iorvr(i), i=i_fivr_ml,i_lavr_ml -> indices of ordered var.

| 26 | ! 'nml' related to local variables
|

| 31 | ! latms1(i_ms),latms2() - range of atoms of i-th m.s
|
|---|
| 32 | !
