Syntax

Strcat( inout sString : string,
        in    sAppend : string ): string;

Return value

concatenated string

Parameter	Description
sString	Source string. This parameter will contain the concatenated string after the Strcat operation
sAppend	String to append

Example

dcltrans
  transaction TStrcat
  var
    sString1, sString2 : string(100);
    sOutput1, sOutput2 : string(100);
    nBuffer1, nBuffer2 : number;
  begin
    nBuffer1 := Malloc(100); nBuffer2 := Malloc(100);
    sString1 := "Hello "; sString2 := "world!";

    // copy sString1 to output string and append sString2
    Strcpy(sOutput1, sString1); Strcat(sOutput1, sString2);

    // copy strings to buffers and concatenate them
    Strcpy(in nBuffer1, sString1); Strcpy(in nBuffer2, sString2);
    Strcat(in nBuffer1, in nBuffer2);
    Strcpy(sOutput2, in nBuffer1);

    write(sOutput1); writeln;
    write(sOutput2); writeln;
    Free(nBuffer1); Free(nBuffer2);
  end TStrcat;

Output

Hello world!
Hello world!
