Enhance jpq, the Proc processor, to allow external calls to paragraphs
# Previous Release Behavior
The ability to chain to or call paragraphs from a proc did not exist.
# Current Release Behavior
Paragraphs can now be executed from a proc in 2 ways:
(filename paragraph) chain to a paragraph [filename paragraph] call a paragraph and continue execution of the proc
where filename is the name of the file where the paragraph is stored.
For example, given this proc in the MD (or VOC):
ID: EXEC 001 PQ 002 S2 003 (PROK
and this paragraph, stored in a file called PROK which, for this example, holds both Procs and Paragraphs:
ID: PATEST 001 PA 002 DISPLAY "Better a little which is done well, than a great deal imperfectly." -- Socrates
The proc will chain to the paragraph and then termninate:
jsh ~ -->EXEC PATEST "Better a little which is done well, than a great deal imperfectly." -- Socrates jsh ~ -->
Likewise, a paragraph can be called within a proc as in:
001 PQ 002 [PROK PATEST] 003 ODone!
The proc will continue execution after the PATEST paragraph has been executed.
Paragraphs are orthogonal to the proc. In other words, any output from the paragraph does not affect any of the proc buffers; it is an independent process from the rest of the proc.
Paragraphs can exist in any file and can then be run with the para command. For example, if the above paragraph is stored in a file called SCRIPTS then it can be executed with:
para SCRIPTS PATEST
