int e l 1.7 STORAGE ALLOCATION To Summarize: Strings are stored from VARTOP to MTOP. Scalar variables are stored from VARTOP "down" and VARUSE points to the next available scalar location. Dimensioned variables are stored from the end of the user program in RAM "up." If no program is in RAM this location is 518 . DIMUSE keeps track of the number of bytes the user has allocated for dimensioned variables. If DIMUSE >= VARUSE a MEMORY ALLOCATION ERROR is generated - 187 -
