<h2 id="functionality">Functionality</h2> <p>Much like <a href="/facts/Java_(programming_language)/9ScgFyAL">Java</a> and <a href="/facts/Microsoft_.NET/Hh5tWDIw">.NET</a>, PL/B programs are compiled into an intermediate <a href="/facts/Byte-code/EPkMFR7M">byte-code</a>, which is then interpreted by a runtime library. Because of this, many PL/B programs can run on <a href="/facts/DOS/sWwDXNmX">DOS</a>, <a href="/facts/Unix/0pNL2seI">Unix</a>, <a href="/facts/Linux/9FvCKSTq">Linux</a>, and <a href="/facts/Microsoft_Windows/bwhAhuSL">Windows</a> <a href="/facts/Operating_system/8XTuvMh2">operating systems</a>.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> PL/B (Databus) is actively used all over the world, and has several forums on the Internet dedicated to supporting software developers. </p><p>PL/B has a database capability built-in with ISAM and Associative Hashed Indexes,<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a> as well as functionality for working with <a href="/facts/ODBC/2dV2Fm5j">ODBC</a>, <a href="/facts/SQL/UjQLJcYm">SQL</a>, <a href="/facts/Oracle_Database/FHv5g732">Oracle</a>,<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a> sequential, random access, <a href="/facts/XML/clNgUfWk">XML</a> and <a href="/facts/JSON/bs1rUAhd">JSON</a> files.<a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a> </p><p>PL/B also has the ability to access external routines through <a href="/facts/Component_Object_Model/2DtIAufW">COM objects</a>, <a href="/facts/Dynamic-link_library/vySyC1dz">DLLs</a> and <a href="/facts/Microsoft_.NET/Hh5tWDIw">.NET</a> assemblies. Full access to the <a href="/facts/Microsoft_.NET/Hh5tWDIw">.NET</a> framework is built into many versions. </p><p>Several implementations of the language are capable of running as an Application Server like <a href="/facts/Citrix/XffnyLER">Citrix</a>, and connecting to remote databases through a data manager. </p> <h2 id="source-code-example">Source code example</h2> IF (DF_EDIT[ITEM] = "PHYS") STATESAVE MYSTATE IF (C_F07B != 2) DISPLAY *SETSWALL 1:1:1:80: *BGCOLOR=2,*COLOR=15: *P49:1," 7-Find " ELSE DISPLAY *SETSWALL 1:1:1:80: *BGCOLOR=7,*COLOR=0: *P49:1," 7-Find " ENDIF STATEREST MYSTATE TRAP GET_PRO NORESET IF F7 ENDIF IF (SHOW_FILTER AND THIS_FILTER AND C_CUSTNO <> "MAG") LOADMOD "filter" PACK PASS_ID WITH "QED ",QED_ID1,BLANKS MOVE " FILTER DISPLAY (F6) " TO PASS_DESC SET C_BIGFLT CALL RUN_FILT USING PASS_ID,PASS_DESC,"432" UNLOAD "filter" CLEAR THIS_FILTER ENDIF <h2 id="external-links">External links</h2> <ul> <li>Computer programming portal</li></ul> <ul><li><a href="http://www.sunbelt-plb.com">Sunbelt implementation of PL/B</a></li> <li><a href="http://www.sysmaker.com/infopro/x3j15">ANSI PL/B Standards Committee</a></li> <li><a href="http://www.mmcctech.com/pl-b/plb-0010.htm">MMCC PL/B programming notebook</a></li> <li><a href="http://www.dbcsoftware.com/dbcov.html">DB/C DX, DATABUS, and PL/B Overview</a></li> <li><a href="http://bitsavers.trailing-edge.com/pdf/datapoint/software/50004_databusSimpUG_Feb76.pdf">Databus Simplified User Guide</a></li></ul> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>"J15 - Programming Language PL/B". sysmaker.com.
