Equivilant to the input.<br /> <br /> === Destroys ===<br /> * All<br /> <br /> == Remarks ==<br /> * This routine will not check to see if there is insufficient RAM.

The user must do this himself.<br /> * DE cannot be the first byte of the variable's data or else the symbol entry's pointer to the data will become corrupt (the first byte being the size field?).<br /> <br /> == Example ==<br /> ld hl,9<br /> B_CALL EnoughMem<br /> jr c,NotEnoughMem ;make sure there is enough memory to insert the RAM<br /> <br /> ld hl,ApplicationVariable<br /> rst rMov9ToOP1<br /> B_CALL ChkFindSym ;find the application variable<br /> jr nc,AppVarNotFound<br /> <br /> inc de<br /> inc de ;move past the size bytes<br /> <br /> ld hl,9<br /> B_CALL InsertMem ;insert 9 bytes here<br /> <br /> ex de,hl<br /> dec hl<br /> ld a,(hl)<br /> dec hl<br /> push hl<br /> ld h,(hl)<br /> ld l,a ;ld hl,(de).
