! Gawk.Cld -- command defintion for GAWK
! Pat Rankin, Nov'89
! [ revised for 2.12, May'91 ]
! [ revised for 4.0.0, Feb'11 ]
!
! This command definition is compiled into an object module which is
! linked into all three programs, GAWK, DGAWK, and PGAWK, and it is
! not able to use syntax-switching qualifers to invoke the different
! images gawk.exe, dgawk.exe, and pgawk.exe. To use dgawk or pgawk
! when this command definition is installed as a native command, use
! $ define gawk location:dgawk.exe
! or $ define gawk location:pgawk.exe
!
module Gawk_Cmd
define verb GAWK
synonym AWK
! image gawk !usage $ DEFINE GAWK disk:[directory]GAWK
parameter p1, value(required,list), label=gawk_p1, prompt="data file(s)"
qualifier input, value(required,list,type=$infile), label=progfile
qualifier commands, value(required), label=program
qualifier extra_commands, value(required), label=moreprog
qualifier field_separator, value(required), label=field_sep
qualifier variables, value(required,list)
qualifier usage
qualifier copyright
qualifier version
qualifier lint, value(list,type=lint_keywords)
qualifier posix
qualifier strict, negatable !synonym for /traditional
qualifier traditional, negatable
qualifier re_interval, negatable !only used with /traditional
qualifier sandbox
qualifier debug, negatable !obsolete; debug via separate DGAWK program
qualifier output, value(type=$outfile,default="SYS$OUTPUT")
qualifier optimize, negatable !actually on always; negation is ignored
qualifier profile, value(type=$outfile,default="awkprof.out")
qualifier dump_variables, value(type=$outfile,default="awkvars.out")
qualifier non_decimal_data
qualifier characters_as_bytes
qualifier use_lc_numeric
qualifier gen_pot
qualifier reg_expr, value(type=reg_expr_keywords) !(OBSOLETE)
disallow progfile and program !or not progfile and not program
!disallow lint.warn and (lint.fatal or lint.invalid)
define type lint_keywords
keyword warn, default
keyword fatal !lint warnings terminate execution
keyword invalid !warn about invalid constructs but not extensions
keyword old !warn about constructs not available in original awk
define type reg_expr_keywords
keyword awk
keyword egrep, default !synonym for 'posix'
keyword posix !equivalent to 'egrep'
!
! p1 = data file list (possibly including 'var=value' contructs)
!note: parameter required; use 'sys$input:' to read data from 'stdin'
! /input = program source file ('-f progfile')
! /commands = program source text ('program')
!note: either input or commands, but not both; if neither, usage message given
! /extra_commands = additional program source text; may be combined with /input
! /field_separator = character(s) delimiting record fields; default is "[ \t]"
! /reg_expr = obsolete
! /variables = list of 'var=value' items for assignment prior to BEGIN
! /posix = force POSIX compatability mode operation
! /sandbox = disable I/O redirection and use of system() to execute commands
! /strict = synonym for /traditional
! /traditional = force compatability mode operation (UN*X SYS V, Release 4)
! /re_interval = for /traditional, regular expressions allow interval ranges
! /output = destination for print,printf (default is sys$output: ie, 'stdout')
! /lint = scan the awk program for possible problems and warn about them
! /optimize = parse-time evaluation of constant [sub-]expressions only
! /debug = debugging mode; no-op unless program built using `#define DEBUG'
! /dump_var = at program termination, write out final values for all variables
! /profile = collect all parts of the parsed awk program into awkprof.out
!note: use separate pgawk program to collect run-time execution profiling
! /usage = display 'usage' reminder [describing this VMS command syntax]
! /version = show program version and quit; also shows copyright notice
! /copyright = show abbreviated edition of FSF's copyright notice and quit
