Abbreviations Dictionary

Abbrev	Meaning	Location, Use, Cross Ref's	Sample Actual Usage
lp	long pointer	Usually found as a prefix to variable names. NARS makes frequent use of pointers to speed up processing times, to make NARS2000.exe more efficient.	lptkRhtArg (var name; long ptr to token var structure of a right hand argument for a function call)
NELM	Nested Element	Usually embedded within variable names.	APLNELM aplNELMRht; // Right arg NELM for variable type APLNELM and variable named aplNELMRht
PerTab	permanent table	Embedded in var names. Detailed explanation of PerTab found in C source header file <pertab.h>.	LPPERTABDATA lpMemPTD; where LPPERTABDATA is the variable type and lpMemPTD is a pointer to PerTabData global memory
PTD	permanent table of data	Embedded in var names.	lpMemPTD structured var name, in this case a ptr to PerTabData global memory
SIS	State Indicator Stack	Frequently embedded within variable and function names. Detailed explanation of SIS found in C source header file <sis.h> See also APL's System Command )SI.	lpMemPTD->lpSISCur->ResetFlag; (var name) AND FillSISNxt (fcn name)
