* until the end of the current SET command. This way any remaining commands in the current parse line will be
* parsed and triples generated for them. This is necessary just in case the currently parsed invalid SET command
* does not get executed at runtime (due to postconditionals etc.)
*
* Some comment on the need for "first_setleft_invalid". This variable is needed only in the
* case we encounter an invalid-SVN/invalid-FCN/unsettable-SVN as a target of the SET. We need to evaluate the
* right-hand-side of the SET command only if at least one valid setleft target is parsed before an invalid setleft
* target is encountered. This is because we still need to execute the valid setlefts at runtime before triggering
* a runtime error for the invalid setleft. If the first setleft target is an invalid one, then there is no need
* to evaluate the right-hand-side. In fact, in this case, adding triples (corresponding to the right hand side)
* to the execution chain could cause problems with emit_code later in the compilation as the destination
* for the right hand side triples could now be undefined (for example a valid SVN on the left side of the
* SET would have generated an OC_SVPUT triple with one of its operands holding the result of the right
* hand side evaluation, but an invalid SVN on the left side which would have instead caused an OC_RTERROR triple
* to have been generated leaving no triple to receive the result of the right hand side evaluation thus causing
* emit_code to be confused and GTMASSERT). Therefore discard all triples generated by the right hand side in this case.
* By the same reasoning, discard all triples generated by setleft targets AFTER this invalid one as well.
* "first_setleft_invalid" is set to TRUE if the first setleft target is invalid and set to FALSE if the first setleft
* target is valid. It is initialized to -1 before the start of the parse.

/* Some explanation: The triples from the left hand side of the SET expression that are
* expressly associated with fetching (in case of set $piece/$extract) and/or storing of
* the target value are removed from curtchain and placed on the targchain. Later, these
* triples will be added to the end of curtchain to do the finishing store of the target
* after the righthand side has been evaluated. This is per the M standard.
*
* Note that SET $PIECE/$EXTRACT have special conditions in which the first argument is not referenced at all.
* (e.g. set $piece(^a," ",3,2) in this case 3 > 2 so this should not evaluate ^a and therefore should not
* modify the naked indicator). That is, the triples that do these conditional checks need to be inserted
* ahead of the OC_GVNAME of ^a, all of which need to be inserted on the targchain. But the conditionalization
* can be done only after parsing the first argument of the SET $PIECE and examining the remaining arguments.
* Therefore we maintain the "curtargchain" variable which stores the value of the "targchain" at the beginning
* of the iteration (at the start of the $PIECE parsing) and all the conditionalization will be inserted right
* here which is guaranteed to be ahead of where the OC_GVNAME gets inserted.
*
* For example, SET $PIECE(^A(x,y),delim,first,last)=RHS will generate a final triple chain as follows
*
* A - Triples to evaluate subscripts (x,y) of the global ^A
* A - Triples to evaluate delim
* A - Triples to evaluate first
* A - Triples to evaluate last
* B - Triples to evaluate RHS
* C - Triples to do conditional check (e.g. first > last etc.)
* C - Triples to branch around if the checks indicate this is a null operation SET $PIECE
* D - Triple that does OC_GVNAME of ^A
* D - Triple that does OC_SETPIECE to determine the new value
* D - Triple that does OC_GVPUT of the new value into ^A(x,y)
* This is the point where the conditional check triples will branch around to if they chose to.
*
* A - triples that evaluates the arguments/subscripts in the left-hand-side of the SET command
* These triples are built in "curtchain"
* B - triples that evaluates the arguments/subscripts in the right-hand-side of the SET command
* These triples are built in "curtchain"
* C - triples that do conditional check for any $PIECE/$EXTRACT in the left side of the SET command.
* These triples are built in "curtargchain"
* D - triples that generate the reference to the target of the SET and the store into the target.
* These triples are built in "targchain"
*
* Note alias processing does not support the SET *(...)=.. type syntax because the type of argument
* created for RHS processing is dependent on the LHS receiver type and we do not support more than one
* type of source argument in a single SET.
