PM40766: JCL VARIABLE NOT RESOLVED ON FIRST REFERENCE IF DEPENDENT AND POSITIONAL

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• If a DEPENDENT JCL VARIABLE is referenced in a given JCL first
  as a "normal)" ("%") variable, then as a positional (?) variable
  the first reference as a positional variable may not be resolved
  correctly.  The variable value may be resolved as BLANK.
  .
  For instance given this JCL:
  //*%OPC TABLE NAME=(PBAMTSTV)
  //*%OPC SETVAR T1=(CYY+1YR)
  //*%OPC SETVAR T2=(CYY-2YR)
  //*T1       :<&T1.>
  //*T2       :<&T2.>
  //*CMM      :<&CMM.>
  //*MTV331A  :<&MTV331A.>
  //*MTV331   :<&MTV331.>
  //DUMMY    EXEC PGM=ICEGENER
  //SYSPRINT DD SYSOUT=*
  //SYSUT1   DD *
  THIS IS TEST CARD 1           <&MTV331A.>   <      ?46MTV331
  THIS IS TEST CARD 2           <&MTV331A.>   <      ?46MTV331
  //SYSUT2   DD SYSOUT=*
  //SYSIN DD DUMMY
  /*
  The two TESTCARD lines resolve as:
  THIS IS TEST CARD 1           < >   <
  THIS IS TEST CARD 2           < >   <        1           08

  as BLANK.
