Difference between Define and Perform

[Former Member]

Hi all!

Is there a difference between macros and perform? assuming that the routine will not return any values...

For example, I want to concatenate 3 fields into a single field on another table:

1)

DEFINE add_line.

concatenate &1 &2 into tab2-field1.

append tab2.

END-OF-DEFINITION.

2)

PERFORM add_line USING text1 text2.

concatenate text1 text2 into tab2-field1.

append tab2.

ENDPERFORM.

Which one would be better to use?

Thanx

well you cannot debug makros, so try to avoid them where possible

hi,

perform is more useful for the most of the cases.

Hi,

Go for PERFORM statement, we can not debug the Macros for checking values in debug mode.
