Visual Basic 6 (a.k.a. VB6) is an out-of-date programming language developed by Microsoft. Though it is very popular and well known.

Here is a reference chart which list VB6 functions and commands and their equivalents in Business Rules!.


BR! VB6
 ! '
A$(3:4) mid(A$,3,2) [1]

Left Right

Ctrl+A Ctrl+Break

(only works during development time, not after being compiled)

Chr$ Chr$
Date$ Format$ [2] and Now
Env$("[variable]") Environ$("[variable]")
Cnvrt$ Format
DimOnly Option Explicit

(similar but different in scope)

LTrm$ LTrim$
LwrC$ LCase$
Pos InStr and InstrRev
RTrm$ RTrim$
SRep$ Replace$
Trim$ Trim$
UprC$ UCase$
Max (no equivalent)
Print Bell; Beep
UDim(xArray) CStr(xArray.length)
Option Base 1 and Option Base 0 "Option Base 1, will force VB to default the lower bound of arrays to 1. The Option Base statement can only have the number 0 or 1 after it, and 0 is the default – so you never need to code Option Base 0" [3] Note that the defaults in BR! and VB6 are opposite.
Mat To change the size of an array use Redim or ReDim Preserve (to also keep the existing values) [4]
Else If ElseIf (note the missing space)
Status Stacks Call Stack available from the Debug Toolbar
Free Kill
if exists("C\What\File.txt")<>0 then If Dir("C\What\File.txt")<>"" Then
