to wait a given delay time is this available in gpc?

Not yet for Linux. You can use the `select' function from the system library to implement it:

Wouldn't it be easier to use usleep(3), like: procedure usleep (usec: MedCard); C; inline procedure Delay (msec: Integer); begin usleep (1000 * msec) end; This is for Linux. Other platforms may vary... -- Frank Heckenbach, Erlangen, Germany fjf@gmx.de http://home.pages.de/~fjf/links.htm
