Does anyone remember how many bytes an integer and a Float where in BlitzBasic? I'm still using it and I like it?

Wouldnt it depend on the processor you were compiling towards?

nah, not these days. An Integer is 4, I think float is 8 (hense the term double) but could be wrong about the float. I guess a Integer could be 64bits (thus 8 bytes) on a 64 bit processor but I'm pretty sure that Blitz Plus WON'T make use of that without being recoded.

***ALWAYS***
integer = 4 Bytes
float = 4 Bytes

well there you go. I'm used to Delphi where a Float (called Extended) IS 8 bytes and on older systems an Int was only 16-bit.

Dunno why this one disappeared from the archives... it *was* there. Anyway, handy function working with banks, and you want to inspect bytes, shorts, ints, floats.

MonitorBank bank ; the other 2 arguements are not for you :P
Function MonitorBank(bank,action$="",dat$="")


	;
	; MonitorBank, Blitzplus
	;
	; by CS_TBL
	;
	; usage:	MonitorBank MyBank
	;
	; The function is completely stand-alone
	; LeftMouseButton on the canvas: cycle through decimal-, hexademical- and ascii-viewmodes
	; Out of lazyness, not all ASCII codes below 32 are supported, also because of a lack of pixels.. :-)
	;


	; look all !
	
	If Not bank Return

	Select action$
	
		Case "" ; setup/(main)/end
