I am having the following script:(Message 1)
MVSALIAS INPUT=UH1,HLQ.XXXX.YYYY.DATA,SEQ /O
RESALIAS OUTPUT=XXX00000,PUBLIC_TCS /O
COPY INPUT: OUTPUT:502PPOAF.DB /R0

This script is used as:(Message 2)
QCONNECT QNAME=XXXX TCSUSER=XXXXX TCSPSWD=XXXXXX MVSPSWD=XXXXXX
JADD JOBNAME=SXXXX,
QNAME=XXXX,
SCRIPT="Dataset in which the message 1 is present".
The above message 2 is kept in a DataSet and given as input to a program.

I dont have that program with me(I only have the load module) .

1)What does the Messsage-1 mean?
2)What do we mean by the .DB extension files. Is that my shop dependent or is it a general extension?

I suspect if it is FTP process,but Iam not able to undersatand the Syntaxes used. How can I get the info(No one in my team is aware of this).

Thanks much,
Thrivikram.
