RE: retrieve user space api problem

["Bob Cozzi" <cozzi@xxxxxxxxx>]

You should be using the RPG ToolKit to do this kind of stuff; all the
difficulties you're seeing are hidden in the Toolkit API wrappers.
Having said that, a Bin(4) value is in fact a 10i0 value in RPG IV.
However it occupies 4 bytes of storage. So to get the value, use %SUBST(x :
pos : 4) and store it in a Char(4) field that is overlaid on top of a 10I0
value, as follows:
D            DS
D  szChar                  4A
D  nOffset                10I 0  Overlay(szChar)

C               eval  szChar = %subst(buffer : POS : 4)

Subject: retrieve user space api problem

hi,

i have problems retrieving binary(4) data from user space. the char data
is ok. but i have problems getting binary(4) fields like 

124     7C      BINARY(4)       Offset to list data section

if i use the display command in my rpg program i get:

DSPLY  b

i tried to convert it to a number with:

listPosition = %dec(%trim(listValue) : 10 : 0);

but i get an error with errorcode 105 (which seems to be undocumented or
at least i can't find the docu of that status) when i look at the status
field of the program error data structure.

i think i make some terribly simple mistake but i don't get it. perhaps
someone can help me.

thanx in advance.

mk
