Are there any suggested alternatives for creating VSAM files with record sizes exceeding the File Handler record length limit of 62KB? Attempting to allocate a dataset exceeding this limit results in a  JCLAM0142S Error.

Hi Sebastian,

What does the DSB/Catalog entry configuration entry look like?
Have you considered to store the data in a Sequential File instead of VSAM to see if that can help?
