can-do or look-up

[Kalan]

Hi all,

I am trying to trace the required string in the comma separated concatenated string variables
(both the variables are longchar data type) using can-do or lookup. but receiving the below error.
[FONT=r_ansi][FONT=r_ansi]'Incompatible data types in expression or assignment. '

I have used 'char' data type variable as a parameters, since the concatenation list string value is big and raised the error
'REPLACE/CONCAT may not result in data > 32000 bytes. (11678)' In order to resolve this i preferred longchar data type.

Can someone pls advise on this?

Thanks.

The INDEX function can use LONGCHARs. You will need to ensure that both your source and target strings have leading and trailing separators.

DEF VAR lcc1 AS LONGCHAR INIT ",one,two,three,".
DEF VAR lcc2 AS LONGCHAR INIT ",two,".

MESSAGE INDEX( lcc1, lcc2 ) > 0.

The lookup function does support the longchar data-type, so i see no reason why to switch to the index function.

OP was using CAN-DO. There are two alternatives for CAN-DO:

1. lookup (of which the list can be a longchar, but the search string cannot)
2. index (of which both can be longchar)
