Have you tried to use /usr/xpg4/bin/awk or gawk ?

A commented and revised version of the script :
Code:
awk '

#
# Input file #2
#

NR==FNR {                               # Select records from input file #1
   tbl[$1]++;                           #   Memorize table in in array tbl
   next;                                #   Proceed next record
}

#
# Input file #2
#

/ALTER TABLE/ {                         # Select ALTER TABLE records
   tbl_name = $3;                       #   Table name
   getcols = (tbl_name in tbl ? 1 : 0); #   Set getcols flag if table
                                        #   + found in array tbl
   next;                                #   Proceed next record
}

! getcols {                             # Select record if getcols flag not
                                        # + set to 1
   next ;                               #   Proceed next record
}

/^ADD/,/;[[:space:]]*$/ {               # Select ADD records (from ADD to
                                        # + record endig with ";"
   f = ($1 ~ /^ADD/ ? 3 : 1);           #   IF ADD record, column name is field 3
                                        #   + otherwise field 1;
                                        #   + column format is field f+1
   sub(/).*/, ")", $(f+1));             #   Remove chars after ) ending column def
   printf "%-12s %-12s %s\n", tbl_name, $f, $(f+1); #  Output table name,
                                                    #  + column name and format
}

' alisha.nam alisha.tmp

"name" file (alisha.nam):
Code:
tbla
tblc

"temp" file (alisha.tmp) :
Code:
ALTER TABLE tbla
ADD  ( cola1  VARCHAR2(11),
       cola2  VARCHAR2(12)  );

ALTER TABLE tblb
ADD  ( colb1  VARCHAR2(21),
       colb2  VARCHAR2(22)  );

ALTER TABLE tblc
ADD  ( colc1  VARCHAR2(31),
       colc2  VARCHAR2(32),
       colc3  VARCHAR2(32)  );

Output:
Code:
tbla         cola1        VARCHAR2(11)
tbla         cola2        VARCHAR2(12)
tblc         colc1        VARCHAR2(31)
tblc         colc2        VARCHAR2(32)
tblc         colc3        VARCHAR2(32)

ALTER 
GROUP(7) SQL Commands ALTER GROUP(7) NAME
ALTER GROUP - change role name or membership SYNOPSIS
ALTER GROUP groupname ADD USER username [, ... ] ALTER GROUP groupname DROP USER username [, ... ] ALTER GROUP groupname RENAME TO newname DESCRIPTION
ALTER GROUP changes the attributes of a user group. This is an obsolete command, though still accepted for backwards compatibility, because groups (and users too) have been superseded by the more general concept of roles. The first two variants add users to a group or remove them from a group. (Any role can play the part of either a ``user'' or a ``group'' for this purpose.) These variants are effectively equivalent to granting or revoking membership in the role named as the ``group''; so the preferred way to do this is to use GRANT [grant(7)] or REVOKE [revoke(7)]. The third variant changes the name of the group. This is exactly equivalent to renaming the role with ALTER ROLE [alter_role(7)]. PARAMETERS
groupname The name of the group (role) to modify. username Users (roles) that are to be added to or removed from the group. The users must already exist; ALTER GROUP does not create or drop users. newname The new name of the group. EXAMPLES
Add users to a group: ALTER GROUP staff ADD USER karl, john; Remove a user from a group: ALTER GROUP workers DROP USER beth; COMPATIBILITY
There is no ALTER GROUP statement in the SQL standard. SEE ALSO
