EDIT$–Fieldata Image Composition Editing Package
SAVE3
NDP
NDF
SIGN
ZERO
FCOL
SCALE
VALUE
Used to save X3 during edit mode.
Number of digits to be edited before the decimal point.
Number of digits to be edited following the decimal point.
Nonzero if the floating-point number being edited is negative.
Nonzero if the floating-point number being edited was not normalized.
Contains information to facilitate proper positioning of the edited result.
Used to build the exponent.
Used to save intermediate results (two words). (Used only by floating point.)
Packet Generation
Two procedures are available to generate a packet for EDIT$. The E$PKT procedure
generates a 6-word packet, and the E$PKTF procedure generates a 10-word packet
suitable for floating-point editing. The format of the procedure calls is
E$PKT il,iloc [‘MSG’,EMSG$-stop]
E$PKTF il,iloc [‘MSG’,EMSG$-stop]
[‘FPS’,fps-number] [‘FPR’,fpr-number]
[‘DPC’,dpc-char] [‘SPC’,spc-char]
The optional lists override the assumed values to be placed in the fields msg, fps, fpr,
dpc, spc. The assumed values are msg = '&', fps = 1, fpr = 1, dpc = 0, and spc = 0.
The format of an override list consists of the name of the field enclosed in quotes, a
comma, and the value to be used. For example, the following PROC reference
generates a packet that edits floating-point numbers in a format similar to that used by
FORTRAN:
PKT E$PKTF 22,LINE ‘FPS’,0 ‘FPR’,0 ‘SPC’,’E’ ‘DPC’,‘D’
