Subject: [foxboro] set_confirm for boolean
Hi all,
I am trying to set a boolean from whitin a c-program.
I use the following code : (part of the programm)
data_len=4;
strcpy(temp,"UCM4:CHECKSAP.IN");
x2=1;
status=OM_BOOL;
rtn=set_confirm(temp,VARIABLE,0,&x2,&status,&data_len);
My problem : whatever I use for x2 (0,1, true,T, false,F) the input of the
bloc does not change.
when I use 0 or 1 I declare x2 as an integer, for Trur,T,False or F I
declare x2 as char.
In the manual (BO193BC) page 19 under set_confirm they say for OM_BOOL is a
byte with True/False values only.
Can somebody explain what I am doing wrong ?
Thanks in advance,
Ronny
