Answer
# 2
yes, it is necessary to have declare table in dclgen.
without declaring the table we cant able to define the host
variable of what data type and length of data type.... the
not needed part is
dclgen table(xxxx)
library(yyyy)
action(add)
quote
this is not needed because the declare and host variable
definition can be hard coded into the pgm.
 
Is This Answer Correct ?    2 Yes 2 No
