Opening something in Hexadecimal

hex$(number) converts to hex
val("&h"+text) converst from hex.
you might want to zero pad the hex number

t$=hex$(asciivalue)
if len(t$)<2 then t$="0" + t

or perhaps

t$=string$(2-len(t$),&h30)+t$ 'adaptable to padding to more than 2 places.

How do I open something up in hexadecimal in Qbasic, then edit it?

Read it

Code:

CLSPRINT "First 5 characters in test.exe"PRINTDIM X AS STRING * 1OPEN "test.exe" FOR BINARY AS #1FOR i = 1 TO 5  GET #1, i, X  PRINT ASC(X);NEXT iPRINTCLOSE #1

To write, use PUT.

If you want hex, then convert the ASCII.
