1) PQN is the opening line of a Proc file. In Proc the "T" command outputs to "display", and the "C" switch tells it to issue a "clearscreen".
2) To get an understanding of Pick (or jBASE) go to www.jes.com, and look for Jonathan Sisk's Pick book. Background History of Proc / Comparison with Paragraphs ------------------------------------------------------------------------------------ Universe, (and jBASE) is based on the Pick system, uses Paragraphs to create batch files. Paragraphs start with a PA on line 1 and take the form of normal command line statements. eg PA LIST FILE BY FIELD FIELD1 FIELD2 Before paragraphs existed there was another batch language, called Proc (for Procedural Language). Procs start with PQ (or PQN) in line 1. Because Universe was designed to be able to cater for every type of Pick system that would want to upgrade into it, it also caters for Procs (backward compatible) Proc worked a bit like Assembler, in that its input and output was done using buffers. Commands in Proc had to be loaded onto a stack and then executed. eg PQ HLIST FILE BY FIELD FIELD1 FIELD2 P where H loads the statement onto the stack, and P processes it. In proc the command to display something on screen, a bit like a java println(), is T and the switch to clear the output is a capital C, so T C outputs a "clear screen" to the display... 2008/12/27 Senthil Kumaran <[email protected]> > > Hai Darshan, > > I created this VOC entry and > > Successfully excuted....... > > Can i know the meaning of each line in this program..... > > Also i want to learn on JBASE concept and programming, Can u prefer the > name of Jbase book > > and list of author of it... > > Thanks and Regards, > > Senthil > On Wed, Dec 24, 2008 at 11:17 PM, Darshan KSV <[email protected]>wrote: > >> Create a VOC by name CLS (or anything you like) as follows: >> >> *File VOC , Record 'CLS' >> Command-> >> 0001 PQN >> 0002 T C* >> >> Save it.
