parameters and common variables on Meldas 500L

Hi to everyone,

I'm trying to use DPRNT on an old Meldas 500L (Cincom L32).
I would send via serial port some parameters related to the machine status but I'm not able to find the right #number.
In details:
1. # for program number (Oxxx)
2. # for date and hours
3. # for timer
4. # for pieces counter

I have also a problem with common variables (#100...) because I'm not able to find the right parametr to share these variables between $1 and $2.
At the moment if I write for example #102=2 in $2 system, no errors are displayed but the program doesn't use the right value associated.
Any suggestion?

Thanks in advance
