I am trying to do some substitutions using the substitution operator (:%s) in a text file.
I want to replace all A1, A2, A3.......A100 in my text file.
I used :%s/A2/SAE/g successfully until A9 but when I use A1, all the A11 to A19 is changed. How do I specify the exact match here? (8 Replies)

px_put_recordn
PX_PUT_RECORDN(3) Library Functions Manual PX_PUT_RECORDN(3)
NAME
PX_put_recordn -- Stores record in Paradox file at certain position
SYNOPSIS
#include <paradox.h>
int PX_put_recordn(pxdoc_t *pxdoc, char *data, int recpos)
DESCRIPTION
Stores a record in the buffer data into a Paradox file at the given position recpos. The first position has number 0. The function will
determine the data block for this record. If the position is after the last data block, then as many as needed empty data blocks will be
added. If the position is in the middle of a data block and there is no record right before the position, then the position will be recal-
culated to make sure the new record will be stored in the first free slot of the datablock. For example, if a datablock contains H records
and the first call of PX_put_recordn wants to store a record at postion 11, then this will be corrected to position H. PX_put_recordn will
also add an empty data block and store the record as the first record of the second data block. Storing a second record at position 11
again, will be executed without any position change.
data must be constructed with PX_put_data_xxx(3) functions before. It is of the same structure as the record returned by PX_get_record(3)
and PX_get_record2(3).
RETURN VALUE
Returns the record position on success and -1 on failure. The first position has number 0.
