The basic unit of work in compiled SOUL is the "quad." Every SOUL statement generates one or more quads. By breaking down Model 204 processing by quad types (using the QUAD parameter on STATE reports), you can get an idea of the general type of work occurring in an Online.

To interpret a QUAD report, it is important to know what the individual quads do. $Function quads are easy to interpret since they are listed by function name. Other quads are listed here with a brief description of their function.

Model 204 quads
ADDAV Add a fieldname/value pair to a record. Can be an ADD statement, part of a CHANGE statement or one line in a STORE RECORD statement.
INSERT Add a fieldname/value pair to a record for the INSERT statement.
ANDQ Perform a logical AND in a 204 expression (possibly in an IF statement).
ARADD Perform an arithmetic addition in an expression.
ARDIV Perform an arithmetic division in an expression.
ARMUL Perform an arithmetic multiplication in an expression.
ARSUB Perform an arithmetic subtraction in an expression.
ASSQ Assigns result (possibly intermediate) of an expression to a result variable.
ASSQCN Assigns integer constant to a (possibly intermediate) fixed result variable.
ASSQEE Assigns result (possibly intermediate) of a string expression to a string result variable.
ASSQNN Assigns result (possibly intermediate) of a numeric expression to a numeric result variable.
ASSQO Assigns Blob field value to the user buffer.
AUDITUS The part of the AUDIT statement that actually moves data into the journal.
BACKOUT The BACKOUT statement.
BAND Boolean AND. Combine two bit maps as part of FIND statement or in list manipulation.
BASE Handles the SFGE$ and SFL$ conditions in a FIND statement.
BEQVAL Handles the field = VALUE IN label condition for an ordered character field, where label refers to an enclosing FOR EACH VALUE loop or to a NOTE statement.
BLIKE Handles the IS LIKE condition on a FIND statement for an ordered character field.
BNOT Boolean NOT. Invert a bit map as part of FIND statement or in list manipulation.
BOPER The part of a FIND statement associated with looking up a a fieldname/value pair in the ordered index. Never occurs in a group context FIND.
BOR Boolean OR. Combine two bit maps as part of FIND statement or in list manipulation.
BRANGE Handles a range find condition for an ordered index field on a FIND statement.
BRNCH Branch used in computed JUMP statement or to branch around subroutine.
BVAL The FIND ALL VALUES statement.
CHGAV Delete a fieldname/value pair from a record for the CHANGE statement.
