in 4gl i am calling a unix script:

LET string = "mailx -s ' ",lc_hosp ,lc_hospname ," Has Updated TCU ' < ",mc_report
RUN string

problem occur when lc_hospname have any special symbol, for example :

lc_hosp = " children's hospital of united state "

when program try to run the string error is "unmatched ' "   (  ' is coming from children's)

can not change the name of hospital. need to mail hospital name as it is.
