The following limits apply to TABLE requests:
An internal sort will be generated automatically under some circumstances, and these have to be counted in the total. HOLD FORMAT FOCUS/XFOCUS will add FOCLIST as a BY field in order to ensure uniqueness.
The internal representation is generated in polish postfix notation, which is significantly smaller than the entered expression. In addition, the constants in expressions (as in DECODE or IF…THEN..ELSE conditions) are stored outside of the expression representations, reducing the space requirement for the expression representation itself.
This means that a total of 511 JOINs can be in effect at any one given time.
Note: FOCUS data sources are limited to 64 segments.
