GetShort( in sString : string, in nPos : number, in nByteOrder : number optional ) : number;
short value
Parameter | Description |
---|---|
sString | BDL string corresponding to the data structure |
nPos | Starting position in the BDL string, where the first position is 1 (not 0) |
nByteOrder |
Specifies the byte order that is applied when a value is retrieved (optional). This parameter can be one of the following:
|
dcltrans transaction TGetShort const SIZE_STRUCT := 32; var myBDLstring : string(SIZE_STRUCT); nShort : number; begin ... // Retrieve a 2-byte signed integer value from position 2 // in the BDL string myBDLstring and thereby (through mapping) get // the element myShort in Struct1 nShort := GetShort(myBDLstring, 2); write("myShort = "); write(nShort); writeln; end TGetShort;
myShort = 209
