PI58250: DSECT UTILITY CONVERTING TO INCORRECT TYPES

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The DSECT utility is generating incorrect variable types for
  'DS AL2' and 'DS AL3' ASM input.  These ASM statements should
  be generated as 'unsigned' types, but the DSECT utility is
  generating them as signed.
