You can use
FileCreate
(then FileWrite):
https://www.freepascal.org/docs-html/rtl/sysutils/filecreate.html
Or
In the link below go the the
File handling
section, there you can find
Text file demo
and
Text File Demo #2
also
improve performance
in the
General
section:
https://wiki.freepascal.org/Portal:HowTo_Demos
To delete a (text) file, you can use
DeleteFile
command:
https://www.freepascal.org/docs-html/rtl/sysutils/deletefile.html
Others useful reading materials:

You could also use the TStringList class which provides a SaveToFile() method.
You can use DeleteFile() to remove a file.

Old school:
AssignFile()
Rewrite()
CloseFile()

I do this when debugging a program with text files...:
Code: Pascal
[Select]
[+]
[-]
with
TStringList
.
Create
do
begin
try
Add
(
'Some variable:'
+
IntToStr
(
somenumber
)
)
;
SaveToFile
(
'file.txt'
)
;
finally
Free
;
end
;
end
;
I delete the file myself after checking it... but you can delete it as here was explained by the other forum members.
