I dont know if this is a typo in your code but the new string that you alloc is called
newText but then you use newText in WinDrawChars.
Also a suggestion, if you are not going to change the DB record then you can do a
DmQueryRecord instead of a DmGetRecord and then you dont need to do a DmReleaseRecord.
Another suggestion, you could write the record directly without copying it to a temp
string first:
recHandle = DmQueryRecord(TestDB,CurrentRecord);
recText = MemHandleLock(recHandle);
FntSetFont(stdFont);
WinSetUnderlineMode(noUnderline);
WinDrawChars(testTxt,20,bounds.topLeft.x,bounds.topLeft.y);
MemHandleUnlock(recHandle);
