Re: Format.m , FortranAssign : weird identifiers for temporary variables

Hi,

the brute force would be to transfrom the 
expression into a string and
use StringReplace[] to the created variables.

| Hi all,
| I'm delighted the Format.m package (1) exists, 
I've dreamt for such a
| package & wish I could have discovered it long 
before...

|
| unfortunately I can't get it to produce an 
optimized code with proper
| identifiers for temporary variables. Instead of 
t1,t2,... I get for
| instance $$1000, $$1001,...
|
| More specifically, although I specify this 
option: AssignTemporary ->
| {"t", Sequence} evaluating
|
| zz = {x -> a/(b c), y -> d/(c e)};
| FortranAssign[Evaluate[First /@ zz], Last /@ zz, 
AssignOptimize -> True]
|
| gives
|
| $$13506=1/c
| x=(a*$$13506)/b
| y=(d*$$13506)/e
|
| instead of
|
| t1=1/c
| x=(a*t1)/b
| y=(d*t1)/e
|
| Does anybody know what to do in such a situation 
?
|
| Thanks very much in advance,
| cheers,
| Nicolas
