RE: 15,5 Revisted (Was Call Query)

I'll side with the people that curse the 15/5 rule.  Yes Richard, you are 
right.  Go ahead, make your RPG program accept 5/2, then try to call that 
sucker from some new GUI application, or make the call to the program from 
some other place, or need to adopt authority, or... It really is a 
nuisance and I can admire any shop that says "No numeric parms".  I get 
burned with this just often enough to swear off using numeric parms.

Just for fun:

Suppose a display file named DISPLAY containing one format that has one
field called PACK defined as numeric five and zero.  Suppose a CL program
named CLPGM containing a SNDRCVF command to display the format.  Imagine 
an
RPG program named RPGPGM that accepts one parameter defined as packed five
and zero.  In CLPGM, immediately following the SNDRCVF, call RPGPGM 
passing
&PACK.  The call will work every time.  Since this will work, then the
statement:

-|> -|You're actually 100% correct.  I *meant* to say,
-|> -|"...has something to do with not being able to pass numerics
-|> -|other than 15,2
-|> -|to RPG programs from CL programs directly..."

is not right.  (I assume that 15,2 really meant 15,5).

As a further example, change the RPG program to accept a packed 9,2
parameter.  Change the CL program in the example above so that it declares 
a
numeric variable called &NUM defined as nine and two.  After the SNDRCVF,
CHGVAR &NUM &PACK then call the RPG program passing &NUM.  This too will
work.

It will also work if the screen declares the parameter with decimals and 
the
&NUM has no decimals - although the digits right of the decimal will be
lost, that is a documented behavior of CHGVAR and it has been that way 
since
1981.

Since I can call an RPG program directly from a CL program and pass a
numeric parameter that is not declared as 15 and 5, I think that I can be
done.

Please post a code fragment that requires 15,5.

If your fragment includes a call to QCMDEXEC or SBMJOB and the command 
line
contains numeric literals, that is a well known and documented situation.
It has been documented to work like this since 1981.

I am being argumentative because this keeps coming up and it just isn't
true.

-|I meant to say 15,5

up

-|
-|You show me a way to:
-|
-|1. Set up a display screen to accept numeric values.
-|2. Pass those values to RPG other than character or 15,5 numeric.
