reading a file with multiple integers on a line

[Tom Morrison]

Just can't seem to find anything that tells me if I can do this and what the syntax would be.

I'd ideally like to be able to read a file into an array.  The file would consist of lines with 2 values per line:  two integers or possibly one or more real numbers and integers intermixed.

Is there a way to do this?

How are the integers separated?  By blanks?  If so, then just

 

INPUT #stream, I AS INT, J AS INT

 

This expects two integers on the stream followed by a new line.  (Well, it will disregard anything following up to the end of line, I think).

 

Alternatively, you can input the whole line and pick it apart.  Say they're separated by a comma.  This is just typed in as a thought experiment, but it should work OK

 

' Read from stream

INPUT #stream, S AS STR

 

' Separate into pieces

LET STRINGS = SPLIT(S, ",")

 

' Check syntax...

IF LEN STRINGS <> 2 THEN ' it's an error, didn't get two comma-separated values.

 

' Convert strings to floats/integers...

LET VALUES = VAL(STRINGS)

 

' If the syntax didn't conform, an error

IF NAN(VALUES(0)) OR NAN(VALUES(1)) THEN ' error

 

' Convert array to integers.

VALUES = INT VALUES

 

' Now have two integers in VALUES(0) and VALUES(1)

PRINT VALUES(0), VALUES(1)
