You are free to invent your own segment names for use with Builder. The only exception is that there is one special, predefined segment called -UNAMED-<\/code> which captures anything in your source files that appears before a <…> segment tag and emits them first.<\/p>\n\n\n\n

In any library functions that we make we will stick as far as possible to the following list of names. It’s a good idea if you use the same names for corresponding function.<\/p>\n\n\n\n

DOCCOSEG<\/code><\/td>Contains any documentation on how to use a library file. DISCARD<\/code> from your builds<\/td><\/tr>
IOSEG<\/code><\/td>Input and output assignments, including analogs<\/td><\/tr>
CONSTSEG<\/code><\/td>Constant values, for example time intervals<\/td><\/tr>
MEQUSEG<\/code><\/td>Contains any mEQU\u00a0RAM<\/a>\u00a0allocations (say for PermStore).\u00a0Must<\/em>\u00a0appear before any\u00a0defBYTE<\/a><\/code>,\u00a0defFloat<\/a><\/code>,\u00a0defSEM<\/a><\/code>\u00a0etc automatic RAM allocations.<\/td><\/tr>
DEFSEG<\/code><\/td>Contains\u00a0automatic RAM allocations<\/a>\u00a0defBYTE<\/code>,\u00a0defSEM<\/code>\u00a0etc. use this only if your prefer (stylistically) to have all your RAM allocations near the start of your program.<\/td><\/tr>
TESTSEG<\/code><\/td>Test code that should always be\u00a0DISCARD<\/code>ed<\/a> from production builds<\/td><\/tr>
INITSEG<\/code><\/td>Initialize code – stuff that should run once at startup. Generally calls initialize routines for various modules\/objects.<\/td><\/tr>
LAUNCHSEG<\/code><\/td>Contains a\u00a0RunTasksForever<\/a><\/code>\u00a0to start up\u00a0MultiTrack<\/a>. Should be used in .b1d files with\u00a0ONEONLY<\/a><\/code><\/td><\/tr>
CODESEG<\/code><\/td>Actual active code. May also contain defXXX memory allocations if you prefer having them inside the module that owns them (c.f.<\/em> near the top of your program.)<\/td><\/tr>

XWIREINIT<\/code><\/td>Contains an instruction (typically\u00a0XwireMaster XwireTab)<\/code>\u00a0that will start up\u00a0Xwire<\/a>\u00a0using the configuration data located under the label\u00a0XwireTab<\/code>\u00a0in NVEM0. Should be used in .b1d files with\u00a0ONCEINLINE<\/a>.<\/code>\u00a0Used by any of our library of Active Template modules that use Xwire.<\/td><\/tr>
XWIREMTAB<\/code><\/td>Contains the line label (typically\u00a0XwireTab)<\/code>in NVEM0 that signals the\u00a0Xwire configuration table<\/a>. Should be used in .b1d files with\u00a0ONEONLY.<\/code>\u00a0Used by any of our library of Active Template modules that use Xwire.<\/td><\/tr>
XWIREMDATA<\/code><\/td>Contains configuration data, in NVEM0, for\u00a0Xwire master operation<\/a>. Used by any of our library of Active Template modules that use Xwire.<\/td><\/tr>

Note that Builder will raise an error if there is a segment name in a .spt file that is not listed in the .b1d file, i.e. you must explicitly\u00a0DISCARD<\/a><\/code>\u00a0unwanted segments. The inverse is not the case: you can have segment names in the .b1d file that do not exist in any .spt file.<\/p>\n","protected":false},"excerpt":{"rendered":"
