Function Result Formatting

Many functions have one or more of the following forms:

• Functions beginning with DTW_r, DTWF_r, and DTWR_r return their results to the function call, so they do not have an output parameter. This example shows the server time:

  Current local time is @DTW_rTIME().
  

• Functions beginning with DTW_m perform the function on multiple parameters. Each parameter behaves as both an input parameter and an output parameter. The function is performed on the parameter and the results are returned in the parameter. This example converts the three input parameters to all capital letters for a consistent look in the display:

  @DTW_mUPPERCASE(model, style, shipNo)
  Shipment $(shipNo) contains $(quantity) of model $(model) $(style).
  

• Other functions beginning with DTW_, DTWF_, and DTWR_ return their results in an output parameter. You must specify the output parameter. This example shows the server time:

  @DTW_TIME(nowTime)
  Current local time is $(nowTime).
