Hi John,
* Convert Long integer into VFP numeric variable
	FUNCTION Long2Num(tcLong)
	DECLARE RtlMoveMemory IN WIN32API AS  AS RtlCopyNum ;
		Long @Dest, String @Source, Long Length
	LOCAL lnNum
	lnNum = 0
	= RtlCopyNum(@lnNum, tcLong, 4)
	RETURN lnNum
	ENDFUNC

>I am converting some data from an old system. I can write the records out to a text file but numeric fields are still in the raw format. I have confirmed that they are 32-bit IEEE floating-point and 32 bit Intiger. Does anyone know where I can find code to convert these? I need to read the 4 bytes and return the decimal value.
>TIA
