; TITLE IBMPAT - Pattern matching routines for IBMSPL
COMMENT &
This module provides the patterns to which incoming records are matched
for two purposes: for 2780/3780 to distinguish console message output from
printer output (though both are actually sent by IBM to the printer) and
to recognize switches embedded in user output which directs IBMSPL where
to put and what to do with the files it receives. This latter function
was called "log file recognition" (or just "recognition" for short) in
D60SPL.

SUBTTL Macros
; Macro - STRNG
;
; Function - To define a word containing the count and address of
; and ASCIZ string.
;
; Parameters - String
DEFINE STRNG (A) <
QQ==0 ;;counter for characters in string
IRPC A,<
QQ==QQ+1
>;end IRPC A
XWD QQ,[ASCII/'A'/]
>;End DEFINE STRNG
; Macro - PATSTR
;
; Function - To define a pattern string and store the STRNG pointer to it.
;
; Parameters - String for pattern
DEFINE PATSTR (A) <
PSTR [STRNG 'A']
>;End DEFINE PATSTR
SUBTTL Console Output Patterns
COMMENT &
This pattern matches up to three characters at the beginning of
a line from the set of space (' '), asterisk ('*') and dollar sign
('$'), followed by either 1 digit or two digits, followed by two
repetitions of .nn where "n" is a digit. For a 2780/3780 printer
file to be considered a log file, all the lines in it must match
this pattern.

SUBTTL Patterns for matching user switches
COMMENT &
The following pattern matches any of the eight legal switches for output
disposition (i.e. PNAME [programmer name], LNAME [log name], LDISP [log
disposition], LFORM [log form type], LSTR [structure for held log file],
LDEST [destination node for printing], ACCOU [user account string], and
ENDLI [end of log parameters]).

SUBTTL Pattern macro support routines

; Returns -
; P1/ Byte pointer

JUMPE T1,.RET ;if no displacement, we are doone
PUSH P,T1 ;save T1
PUSH P,T2 ; and T2
IDIVI T1,5 ;get word displacement into T1 and byte
; displacement into T2
ADD P1,T1 ;add word displacement to byte pointer
MOVE T1,[EXP 44

EXP 44-<2*7>
EXP 44-<3*7>
EXP 44-<4*7>](T2) ;pick up new position field
DPB T1,[POINT 6,P1,5] ;store in byte pointer
POP P,T2
POP P,T1
.RET: POPJ P,
