I am new to this and I have two questions/issues. I have this code:
stringVar CallMemo;
CallMemo := {tbl.col};
Right(CallMemo, InStr(CallMemo, ";") -1)

How I would like it to function is to delete everything before the first semicolon and leave the rest of the memo field. Instead I get the bottom part of the memo field - whatever the instr count is obviously (not all the remaining text after the first .

Also, is there a process that can be incorporated to ignore a memo field if it does not start with a left bracket and contain a semicolon?

thank you!

I think you can use MID function i.e MID(String,Start,LEN),So your code can be written as
stringVar CallMemo;
CallMemo := {tbl.col};
MID(CallMemo, InStr(CallMemo, ";") +1)
this would consider the string from the first ";".
for the Second issue ignore meaning you want to suppress ?
if you want to suppress then right click on the field and suppress (formula)
MID({field},1,1)<>"(" and instr({field},";")<=0
this formula would check if the memo field contains "(" as the first character and the INSTR will check if the field contains ";" .if both conditions satisfies the n the field will be suppressed.

try the solutionl.

I did up using the MID code without a variable. I will try the supression, thanks!
