Here is a quick method that can be used for converting Integer values to Hexadecimal values using 4D code:

If (Count parameters=1) C_LONGINT($1) C_TEXT($0) $0:=Replace string(String($1;"&$");"$";"") End if

If the above code is saved as a project method named UTIL_IntToHex it could be used to convert an integer value to a hexadecimal value like so:

C_TEXT($hex) $hex:=UTIL_IntToHex(77)

In the above example $hex would be equal to "4D".
