VAI. Command

VAriable Indirekt

Intention

This command can be used to assign a Value to a Variable which Name is stored inside another Variable.

The purpose of this command is to be able, to tell a Subprogramm that is called with GSB. or JNF. etc.

where to put the result of the Operation. Also it can be used to emulate Arrays of Variables from 0 to 99.
For example $$H00 to $$H99.

Here is an example.

' Variable gets the Name of another Variable.

' Always use VAB. for that!

VAB.$$OUT=$$INA

' Now here comes VAI.

VAI.$$OUT=1232

' Look what we got.

MBX.$$INA

' This Sample shows what its really good for.

VAB.$$INB=$$INC

GSB.CommandX|$$INB

MBX.$$INC

GSB.CommandX|$$IND

MBX.$$IND

RET.

Here is another example that shows how you can write to Variables $$H01 to $$H99 in a loop using VAI.

FOR.$$LOP|1|99

VAN.$$CNT=$$LOP

FMT.$$CNT|00

VAR.$$HLT=$$H$$CNT

VAI.$$HLT=$$LOP

NEX.

Syntax

VAI.P1=P2
