In the Maketab process, we write the generated Batch Processor control statements to either a temporary dataset or the highlvl.CDBASAMP library. This is determined by the following field on the 'ACM Shadow Table Creation' panel:
Temporary dataset for output => Y (Y or N)
With this set to Y, as above, then the temporary dataset that is used is obtained from the users ISPF ZTEMPF system variable.
This can be displayed by accessing IPPF option 7, Dialog Test, and then 3, Dialog Variables. Use the locate command 'L ZTEMPF' to display the variable.
It is this dataset that does not have sufficient space allocation for the generated statements.
