Luis,

TAG / TAGNO

I dislike the mixture of TAG / TAGNO, and for me the TAGNO, is outdated XBASE from the days of yore. Just do all from a TAG perspective, this is well defined.

DESCENDING

Something is wrong here, the help states
DESCENDING([CDXFileName[, nIndexNumber [, nWorkArea | cTableAlias]]])

If I try on a table like

CREATE CURSOR curTest (i1 I)
INDEX ON i1 TAG _i1
?DESCENDING(_i1,'curTest')
SET ORDER TO _I1 descending
?DESCENDING(_i1,'curTest')

it fails on the first DESCENDING

So, if it runs for your code, i_nm must be a var or a field with a number.

I would rather do ("if .. else" swapped for faster expression and TAG generalized)

Select crMonitorFacturas
lcTag = "I_NM"
If Sys(22,SELECT("crMonitorFacturas")) == m.lcTag  && current index tag
	If Descending(TAGNO(m.lcTag),"crMonitorFacturas")
		Set Order To (m.lcTag) In crMonitorFacturas Ascending
	Else
		Set Order To (m.lcTag) In crMonitorFacturas Descending
	Endif
Else
	Set Order To (m.lcTag) In crMonitorFacturas
Endif

At least this switches for me.

Now you need this as a proc with the TAG as parameter and you are done for any TAG.

Aunt Edit says:
Added SELECT() to SYS(22), so you have all commands with the alias/workarea fitting.

Hi Lutz,

Many thanks again for you help and support.

Best regards,
Luis
