| $$GET(.SEGMENT,SEQ,COMP,SUBCOMP,REP) |
This function gets a value from a segment that was
obtained by calling $$NEXTSEG. The SEQ, COMP, SUBCOMP, and REP parameters are
optional. If not specified, they default to the value1. For example,
$$GET^HLPRS(.SEGMENT,1) will return the value of the first field, first
component, first subcomponent, in the first occurrence. Since many fields
consist of a single simple value, this is a useful feature. $$GET^HLOPRS(0)
may be used to return the segment type.
