Description

The EXEC() function executes a list of commands. Each command is specified by <expC1>, <expC2>, and so on. This function is useful for consolidating command lines in UDCs (User Defined Commands) which have been defined with the ALIAS command. The EXEC() function returns a logical true (.T.) if all the specified commands execute without error, or a logical false (.F.) if an error occurs.

Example

alias lf;
"iif(run('ls –l %1 > run.tmp') = 0,;
exec('textedit([run.tmp],0,0,20,79,.f.,[FILE LISTING])','erase run.tmp'), .F.)"
