What Parser Table Add-ons are Available?

Applies to: RE/m and RE/parser

The following parser tables can optionally be added to the vanilla and RE2.0 parser tables to provide support for ANSI standard M language extensions and for vendor-specific language extensions.

Consult the RE/m reference manual for details of how to configure RE/m to use these parser tables.

Vanilla Parser Add-ons	RE2.0 Parser Add-ons	Purpose
	RE	Permits a comment to occur immediately after a statement, without a preceding space, eg s x=1;comment q:x=1;comment
VAN&	RE&	Support for external package calls. Any external call, with any number of arguments, will be accepted, provided it is syntactically correct.
VAN&ZLIB	RE&ZLIB	Support for the DSM for ULTRIX ZLIB external package. Also includes most, but not all, of the function calls for DSM for VMS. Any function call that is not a valid call to the ZLIB library will be rejected.
Empty	Empty	An empty parser table, used as a starting point for the creation of custom parser tables.
Env	Env	Support for both ^[env]global and ^\|env\|global syntax.
VAN$P	RE$P	Support for the $Principal special variable.
VAN^SPACE	RE^SPACE	Support for references to the global ^<space>, which is used for routine directory information in DSM and MSM systems. For clarity reasons, any reference to ^<space> is stored in the RE/m repository as a reference to ^$ROUTINE.
Zpass		Permits any Z command or function.
	REdsm$zb	Support for the DSM $Zb special variable.
	REdsm$zc	Support for the DSM $Zcall function.
	REdtm$zp	Support for the DTM $Zpiece special variable.
	REdtmfrom	Support for the DTM record manipulation syntax, eg <a,b,c>=^global(x,y,z) s ^global(x,y,z)=<a,b,c>
BadLabel	BadLabel	Permits labels with preceding numeric characters, which most implementations do not treat as an error, eg 4ABC.
VANmerge	REmerge	Support for the Merge command.
View		Permits any View command arguments.
$View		Permits any $View function arguments.
