Finding if an integer value is negative or positive.

Former Member — Fri, 11 Nov 2005 14:02:32 GMT

Hi,

How can I find if a variable which has been defined as an integer is negative or positive?

Ex:

Paramaters: var type i.

When the user enters some value, how can I find if he has entered negative or positive??

Data zero type i value is initial.

...

at selection-screen.
  if var < zero.
    message e999 with 'Value is less than zero'.
  else.
    message e999 with 'Value is greater than zero'.
  endif.

Hello,

If you whant to know that just write:

Data resp type i.

if var < 0.

resp = 0. " Its negative

elseif var >= 0

resp = 1. " Its positive.

....

then use resp to do what you want.

If u have it in the selection screen do a validation in at selection-screen event.

At selection screen.

if p_var < 0.

message e000 with 'the value is negative'.

endif.
