DEL$

[alexfish]

Hi Peter

DEL$(string$ , pos [, delimiter$])
Type: function
Deletes a member at position <pos> from a delimited string$ split by delimiter$. The delimiter$ is optional. If it is omitted, then the definition from OPTION DELIM is assumed. When specified, it may consist of multiple characters.


eg



LOCAL A$ = "THIS TEXT" TYPE STRING

DEL$(A$,2)

produces

Syntax error: could not parse line 98 in file 'utf.bac': "DEL__b2c__string_var(A__b2c__string_var,2)"
Error code recieved : 256

Dear Alex,

The DEL$ function is a function and not a statement. E.g.:

LOCAL A$ = "THIS TEXT" TYPE STRING

A$ = DEL$(A$,2)

Hi Peter

HTH

Hi Peter

still got a problem

LOCAL A$ = "THIS TEXT" TYPE STRING

A$ = DEL$(A$,2)

bacon 3.6 will show text as is

then from 3.6+ to bacon m4 does not show any text

ADDED
APPOLLS

the above does work IE a delimited text in above example

but "THIS" as a string will not.
however I think this statement is possibly misleading and should be updtated with sample code

it may consist of multiple characters.

also tried demo's of sqlite from bacon website

these do not show all the records


PS would it be possible to have a Function to delete a char from a position x

IE Delete char("this is a string",1) = "his is a string"

Hi Again Peter

I am curious about global or declared strings and function

the below produces an error

SUB TEST_IN_MID()

A$ = MID$(A$,1)

PRINT A$

END SUB

DECLARE A$ ="TEST THIS"

A$ = MID$(A$,1)

PRINT A$

A$ ="TEST THIS"


where as declares at top of page work

has this always been the case
DECLARE A$ ="TEST THIS"

SUB TEST_IN_MID()

A$ = MID$(A$,1)

PRINT A$

END SUB



A$ = MID$(A$,1)

PRINT A$

A$ ="TEST THIS"

Hi Alex, this code works fine for me.


LOCAL A$ = "THIS TEXT" TYPE STRING
PRINT DEL$(A$,2)

But also:


LOCAL A$ = "THIS" TYPE STRING
PRINT DEL$(A$,1)
PRINT DEL$(A$,2)

The second PRINT only shows "THIS" because there is no second member in the delimited string. So as far as I can see all works, can you provide a code example which demonstrates that DEL$ is not working?

You can use RIP$ for this. It is the complement of MID$.

Regarding your question about global or declared strings and function: the error you see in the first code snippet is correct, because the function will implicitly declare the the variable "A$" as a global string, before the actual DECLARE statement will declare it.

Thanks Peter

had not notice RIP$ , that one fulfils what I have been looking for in BaCon.

Is latest bacon 4 on downloads or the fossil.
