This is very similar to what Dennis Lovelady just posted... ack, I'm too 
slow... but mine does have some differences from his, so I'm posting it 
anyway:

PGM

    CRTDTAARA  DTAARA(TESTAREA) TYPE(*CHAR) LEN(20)
    MONMSG CPF1023

    ADDENVVAR ENVVAR(QIBM_QSH_CMD_ESCAPE_MSG) REPLACE(*YES) +
              VALUE(Y)
    ADDENVVAR ENVVAR(STMF) REPLACE(*YES) +
              VALUE('/home/klemscot/testfile.txt')
    ADDENVVAR ENVVAR(DTAARA) REPLACE(*YES) +
              VALUE('TESTAREA')

    QSH CMD('cat $STMF | +
             sed -n ''s/.*foo="\(....................\)".*/\1/p'' | +
             datarea -wl $DTAARA.dtaara')

    DSPDTAARA TESTAREA

ENDPGM

Differences between mine & Dennis:

a) Mine assumes the foo= can appear in the middle of other text.  (I'm 
actually assuming you're trying to grab this out of an XML file)

b) Mine assumes data between quotes is always 20 chars, period.  Dennis 
solution will take any length... (maybe I took you too literally)

c) Mine writes the output to a data area, his wrote it to an environment 
variable inside Qshell.

d) If there's more than one foo= string in the file, mine will only take 
the first one.  Dennis' will take them all (but store them all together 
in one variable.)

So... mine is very similar, in some ways better, in some ways worse than 
Dennis'... but I thought it might be worth posting anyway.
