| − | This article attempts to track missing and/or nonstandard features in the current <code>main</code> branch of FreeM. It is a work-in-progress. | + | This article has been superseded by <code>freem_conformance(1)</code> in the UNIX manual. |

| − | == Indirection ==
| |
| − | | |
| − | FreeM supports several forms of indirection that are nonstandard, as well as allowing indirection in several constructs where the standard prohibits it. Below is a list of some known instances of idiosyncratic indirection; please note that this list is by no means comprehensive:
| |
| − | | |
| − | * <code>FOR</code> loops in FreeM support argument indirection
| |
| − | * FreeM supports list indirection, such as <code>S X="1,2,3",ARGS="X,"","",2" W $P(@ARGS)</code>, which will output <code>2</code>
| |
| − | | |
| − | == MERGE ==
| |
| − | | |
| − | * <code>MERGE</code> should be implemented as <code>M[ERGE] postcond SP L mergeargument</code>, but is currently implemented as <code>M[ERGE] postcond SP mergeargument</code>
| |
| − | | |
| − | == KVALUE/KSUBSCRIPTS ==
| |
| − | | |
| − | * Only the inclusive forms of these commands are currently implemented
| |
| − | | |
| − | == Transaction Processing ==
| |
| − | | |
| − | * Restartable transactions are not complete
| |
| − | | |
| − | == Event Processing ==
| |
| − | | |
| − | * <code>ETRIGGER</code> is not yet implemented
| |
| − | * Of the event classes defined in the MDS, only the <code>INTERRUPT</code> ''evclass'' is implemented
| |
| − | * The <code>TRIGGER</code> 'evclass' is nonstandard
| |
| − | * The <code>^$EVENT</code> SSVN is incomplete
| |
| − | * Environment-wide events defined in <code>^$SYSTEM</code> are nonstandard
| |
| − | | |
| − | == Globals ==
| |
| − | | |
| − | == Routines ==
| |
| − | * Dotted routine names are nonstandard
| |
| − | | |
| − | == Locking ==
| |
| − | * The first subscript of ^$LOCK collates according to the rules for global and local subscripts, not as an nref, as FreeM uses globals as backing store for SSVNs. If someone wants to write the code to make this conformant, the maintainer will accept it.
| |
| − | | |
| − | == Miscellaneous Language Features ==
| |
| − | * <code>ASSERT</code> is nonstandard
| |
| − | * <code>WITH</code> and <code>USING</code> are nonstandard
| |
| − | * <code>CONST</code> is nonstandard
| |
| − | * <code>MAP</code> is nonstandard
| |
| − | * <code>WATCH</code> is nonstandard
| |
| − | * <code>THROW</code> is nonstandard
| |
| − | * <code>$DIALECT</code> is nonstandard
