Summary
Function syntax can be a pattern for identifying function calls. This is the approach taken in Thesa. Each function's pattern is a sequence of literals and parameters. Similarly, Planner functions are a pattern which when matched by a goal statement initiates the function. (cbb 5/80)
Subtopic: function patterns 
| Quote: in Galaxy, the syntax for a function call is anything legal that matches a function pattern [»beet5_1989]
| | Quote: a message pattern for a Smalltalk method consists of a selector for matching and parameters for arguments [»xlrg8_1981]
| | Quote: declare operations as a pattern giving data types, operator, and result type [»solnN_1971, OK]
| | QuoteRef: cbb_1973 ;;[reading (QuoteRef: shawCJ_1963) entry descriptor describes a pattern eg integer-class + integer-class
| | Quote: macro Cobol recognizes macro calls by pattern; e.g., 'perform' integer 'times' statement-list 'end-perform' [»triaJM8_1980]
| | QuoteRef: ironET1_1969 ;;32 extend syntax by function definition specifying syntax as well

Subtopic: argument templates
| QuoteRef: cbb_1973 ;;2/8/75 entry must be recognizable
| | QuoteRef: cbb_1973 ;;4/8/79 what is the simplest recognizer-- only variables for parameters, variables identified by capital letters, instruction lookup can be the same as variable lookup. no templated variables.
