Here is the code segment where this error occurs:
Let>i=1
Repeat>i
Readln>somefile,1,resultline
If>resultline=
Message>blank line received
Add>i,1
Until>i,11
Else
Message>data retrieved
Endif
The 'Error in Substring Command' would come up whenever the code goes through the positive case from the if statement.
1. Is this due to the fact that readln to a blank line is tricky to handle by Macro Scheduler? I know the code processed throught the if statement since I did receive the message 'blank line received'.
2. Or is there some trickiness when using an if statement inside a repeat construct?
Please help.
