Look up OpenSeq in help files... or search these forums...

OpenSeq would be BASIC and thus a 'Server' routine, a parallel routine would need to be in C++. Depending on exactly what is in your file, a simple cat may work to 'read' the file.

Shell script is best in doing this, IMHO.

Search the forum for OpenSequentialFile, a server routine that covers all the possiblilities for opening. Choose the one marked version 4.x. Then research ReadSeq, ReadBlk and CloseSeq statements in the DataStage BASIC manual.
