Copies an unsigned short value (2-byte unsigned integer value) into a data structure at a specified position. You must declare a BDL string before using this function.
Kernel.bdh
SetUShort( 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 | Unsigned 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 TSetUShort const SIZE_STRUCT := 32; var myBDLstring : string(SIZE_STRUCT); bOk : boolean; begin // Set a 2-byte unsigned character at position 20 // in the BDL string myBDLstring and thereby (through mapping) set // the element myUShort in Struct1 bOk := SetUShort(myBDLstring, 20, 64000); if bOk then write("myUShort successfully set to 64000");writeln; else write("error setting myUShort"); writeln; end; end TSetUShort;
myUShort successfully set to 64000
