[sqr-users] Global VS parameter list

> Hi,

> I am supposed to modify an SQR report by adding a procedure to it.
> When I add my procedure I passed in a couple of parameters and 1 as return
> parameter.
> Within that procedure I am also referencing some field variables that I
> retrieved earlier.
> 
> However it errored out and complained that the &xxxxx variables that I'm
> referencing are not declared.
> Later I found out that I have to put those variables that I want to use in
> the parameter list of the procedure to make it work.

> For example:
> 
> begin-report
>   let $aa = 'A'
>   let $bb = 'B'
>   do sel
>   do main($aa,$bb)
> end-report
> 
> begin-procedure sel
> begin-select
> 'TESTING'     &dummy
> from dual
> end-select
> end-procedure
> 
> begin-procedure main($in_aa,$in_bb)
>   print $in_aa (1,1)
>   print $in_bb (+1,1)
>   print &dummy (+1,1)
