ASMA157S

Operand must be a simply relocatable expression
Explanation
If there is another message with this statement, this message is
advisory. If this message appears alone, the operand of an ORG or
END statement is not a simple relocatable expression, is too complex,
or is circularly defined. The error might also be that the END operand
symbol is not in a CSECT, or is not an external symbol without addend.

System action
An ORG statement or the operand of an END statement is ignored.

Programmer response
If an error exists, supply a correct expression. Paired relocatable
symbols in different LOCTRs, even though in the same CSECT or DSECT,
might cause circular definition when used in an ORG statement.
