Status: Unverified
FACT(s) (Environment):
OpenEdge 10.1x
SYMPTOM(s):
The LENGTH function returns 0 for variables with space values.
The FORMAT of a variable seems to affect the LENGTH function if the variable contains spaces.
LENGTH function returns 0 for variable with value " "
After upgrading to OpenEdge 10.1x, the LENGTH function does not return the correct length for variables that contain only spaces.
DEFINE VARIABLE c1 AS CHARACTER FORMAT "X" INITIAL " ".
DEFINE VARIABLE c2 AS CHARACTER INITIAL " ".
DEFINE VARIABLE c3 AS CHARACTER FORMAT "X" INITIAL " ".
c3 = " ".
DISPLAY LENGTH(c1) LENGTH(c2) LENGTH(c3).
This code will result in "0 1 1".
CHANGE:
Upgraded from OpenEdge 10.0B.
CAUSE:
This is a known issue being investigated by Development
FIX:
As a work around, assign the variable a space after its definition. For example:
c3 = " ".
