I just use another variable and fill it with the text I want.
Here, I grap a value I call "pCount":
UInt16 YOUR_TEXT_LENGTH = 9, YOUR_OFFSET = 4;
recHandle = DmGetRecord(testDB, CurrentItem);
recText = MemHandleLock(recHandle);
pCountHandle = MemHandleNew(YOUR_TEXT_LENGTH);
pCountText = MemHandleLock(pCountHandle);
// first initiallize it with an array of NULL's
MemMove(pCountText, fillerNineLong, YOUR_TEXT_LENGTH);
MemMove(pCountText, recText + YOUR_OFFSET, YOUR_TEXT_LENGTH);
MemHandleUnlock(pCountHandle);
fldIndex = FrmGetObjectIndex(frm, SPECIFIEDField);
FldSetTextHandle(FrmGetObjectPtr(frm, fldIndex), pCountHandle);
MemHandleUnlock(recHandle);
DmReleaseRecord(CycleCountDB, CurrentItem, 0);
Regards,
Scott
