Hi, Somebody asked to collect difficult items for Turbo Pascal. Evert van de Belt. Board index » Pascal. Yes, I'm new to Pascal. Using TP 4. Whether I use read or readln I can't seem to notice any difference like I can with write and writeln. Also, with a , any disadvantage to not using short-circuiting on boolean expressions. Thank you in advance. The distinctions might seen subtle or absent , but they're not. You have to look at the data "line" that's being read to see what actually happens: 3 7 11 43 2 98 32 0 Read I,J ; will assign 3 to I and 7 to J - and will wait at that point for the next "read" operation.

Thus, a subsequent Read N will assign 11 to N, and so forth. However, Readln I,J ; will assign the same values to I and J - but will flush the rest of the data and start from a new line. The subsequent Read N will assign 32 to N.
