SYNOPSIS
loc = amatch_ (line, from, pat, tagbeg, tagend)
character line(ARB), pat(MAXPAT) integer from integer tagbeg(10), tagend(10) (element "i + 1" returns start or end, respectively, of "i"th tagged subpattern) integer loc returns location/0 matched; if no match, loc is returned as 0
DESCRIPTION
amatch_(3f) scans ’line’ starting at location ’from’, looking for a pattern which matches the regular expression coded in ’pat’. If the pattern is found, its starting location in line is returned. If the pattern is not found, amatch_(3f) returns 0.The regular expression in ’pat’ must have been previously encoded by ’getpat_’ or ’makpat_’. (For a complete description of regular expressions, see the writeup on the editor.)
amatch_(3f) is a special-purpose version of match, which should be used in most cases.
