Copies a short value (2-byte signed integer value) into a data structure at a specified position. You must declare a BDL string before using this function.
Kernel.bdh
SetShort( inout sString : string, in nPos : number, in nShort : number, in nByteOrder : number optional ) :boolean;
true if successful
false otherwise
Parameter | Description |
---|---|
sString | BDL string corresponding to the data structure |
nPos | Insert position in the BDL string, where the first position is 1 (not 0) |
nShort | Short value |
nByteOrder |
Specifies the byte order that is applied when a value is set (optional). This parameter can be one of the following:
|
dcltrans transaction TSetShort const SIZE_STRUCT := 32; var myBDLstring : string(SIZE_STRUCT); bOk : boolean; begin // Set a 2-byte signed integer value at position 2 // in the BDL string myBDLstring and thereby (through mapping) set // the element myShort in Struct1 bOk := SetShort(myBDLstring, 2, -12); if bOk then write("myShort successfully set to -12"); writeln; else write("error setting myShort"); writeln; end; end TSetShort;
myShort successfully set to -12
