SAS requires a description of a dll method in order to use it.
SAS users can run Windows programs using a variety of commands and statements, including X, system(), and Fileref pipes. All these techniques will, on occasion, flash a DOS box window open and close as the command starts and finishes. This flashing is an annoyance.
SAS users can also invoke .dll methods. The following SAS code defines a SASCBTBL interface to the Windows API routine WinExec(). WinExec() runs a Windows program and does not flash a DOS box.
The SAS moduleN() routine can be used in a Data Step or SCL to call the WinExec() routine to run the ppbS program. Example
filename sascbtbl catalog 'work.sascbtbl.winexec.source'; data _null_; file sascbtbl; input; put _infile_; cards4; routine WinExec minarg=2 maxarg=2 stackpop=called module=KERNEL32 returns=SHORT; arg 1 char format=$cstr200.; * lpCmdLine; arg 2 num format=pib2.; * nShowCmd; ;;;;
