PBasic programming: how create, concatenate & use string variables?

Flotul

Hi,

I'm programming a loop calling subroutines. Unfortunately, I can't find the correct syntax. The idea is to concatenate the variable's name + a number (from the counter) but I don't know how to do this. So, here is what it looks like (i. e.) :

MAIN:
DO
idx = idx + 1 // 4 'counter
StringVar = "SubRoutine" + idx 'compose the subroutine's name, should be "SubRoutine0" ... "SubRoutine3"
GOSUB StringVar
LOOP

SubRoutine0:
'process something
RETURN

SubRoutine1:
'process something
RETURN
.....

Possible? Can somebody help?

I think that what you want to do is use ON...GOTO or ON...GOSUB

MAIN:
··FOR idx = 0 TO 3
· ON idx GOSUB ROUT1, ROUT2, ROUT3, ROUT4
· NEXT
· END

ROUT1:
· 'do this
· RETURN

ROUT2:
· 'do that
· RETURN

ROUT3:
· 'do the other
· RETURN

ROUT4:
· 'just do something
· RETURN
·

Hi Allen,

I thank you very muchfor your help; that's a good way to solve my problem.

Nevertheless, I was used years ago to progam under DBase/Clipper and it was quite easy to convert strings to other data formats.

Now, with PBasic, I don't know if the same conversion is possible.

Any idea?

· I think that what you propose (like synthesizing subroutine names from various data elements) is not possible with PBASIC.

· A subroutine name can't include a variable.
· This will not work: a = 150
················· ··· GOTO ROUTa
·

Okay, so it's clear.

Thanks again

DBase and Clipper were designed for BIG machines (PCs), PBASIC for a very small machine (BASIC Stamp). That said, you'll find that PBASIC offers solutions that you need -- just taking a different route. In addition to ON..GOTO and ON...GOSUB, PBASIC also supports SELECT..CASE, which may be more familiar to you coming from a PC background.
