Incrementing a counter.

[Joe Boyle]

in that case, and if you are unhappy using a subfile, add a second line to
set the variable and it should work, 

req gtnxt
acc getnxt
choose reckey n

define dkey int = 1 &
if setsystemval ("NXTKEYVAR" , ascii (nxtkey of gtnxt, n ) )

output gtnxt update
item nxtkey = nxtkey + k
subfile newkey keep include dkey


I always found the subfile creation was necessary to action the setsystemval
in any case.

I would always prefer to use ghost screens for this kind of thing, but I
think it's a little trickier on mpe.

Regards, Joe.

I have an MPE batch job that need to calculate the next number in a
sequence that will be used later on. The previous number is held in an
Image dataset. This number has to be incremented by the batch job prior
to being used. Inline QTP seamed the best/easiest way to do it.

most systems loose the variable after the process is returned from, so
how about add a request to get the next number as below, and then access
a subfile ( which will default to the users local area )

req gtnxt
acc getnxt
choose reckey n
define dkey int = nxtkey of gtnxt
output gtnxt update
item nxtkey = nxtkey + k
subfile newkey keep include dkey

but you can do all of that in quick anyway, and without a subfile, so
why
call a qtp ?

Greetings to the -L,

Using QTP I need to increment a counter in a dataset (MPE/Image) and
return a copy of the incremented value in a system variable via
SETSYSTEMVAL.

Suggestions/examples on how to do it would be welcome.
