.... perhaps...

In regular use (without DSD) the delimiter is blank ('20'x on ascii systems) Adding '09'x to the default just treats it the same as blank. This becomes significant when the DSD option is used when consecutive delimiters imply fields with missing values.

However, when the infile statement doesn't contain DSD you could simplify this dlm='0920'x code and achieve the same effect by just replacing that dlm= option with infile option ExpandTabs. Then the input statements see the text just as we would read it.

From on-line help (v6, v8, win/unix/os390)

EXPANDTABS | NOEXPANDTABS Specifies whether to expand tab characters to the standard tab setting, which is set at 8 column intervals starting at column 9. NOEXPANDTABS is the default. EXPANDTABS is useful if you are reading data that contain the tab character native to your host system.

Shame those code authors were not aware of this option, Regards Peter Crawford
